Procedure: First, gather the needed supplies, which include two (2) meter sticks, stopwatch or other timing devices, and a tennis ball or other throwable object. Find an open place with a high ceiling or go outside; if outside make sure to be at least one hundred (100) yards away from roofs or other surfaces the ball could get stuck on. Next, find the starting height of the ball, which can be done two (2) ways: Find the height of release by fully extending your arm to the maximum height during your throwing motion and then have your partner measure this height. Have your partner hold a meter stick upright at ninety (90) degrees and release the ball during the throw at the same point every time. Designate one partner to time, while …show more content…
This can be done by using differential calculus to the find the function of the velocity of the ball after t seconds, the vertical velocity at a known time during the ball’s motion, and to calculate the maximum height of the ball. This lab also taught us how to apply differential calculus to find the position, time, velocity, and acceleration of an object when given the object’s position versus time
Hold one ball beside the top of the meter stick so it does not touch. Drop the ball. Have your partner record the height of the first bounce.
Lastly, the launch angle also has a great effect on the distance traveled. If projected at 90° the ball would only be thrown vertically upwards and back down to the person. There would be no horizontal change in position but a great maximum height. The greatest horizontal distance is reached between 40° and 50°. For this reason the launch angle affects the
The patient is a 70-year-old gentleman who was playing racquetball fell, hit his head was brought to the ED had a laceration on the right occiput area which was taken care of. He is also on known to be on aspirin. He was made in acute inpatient admission at the 20 to 11 the morning of the 13th. He was discharged a little over 24 hours later. My clinical review of this case indicates that this was most appropriate. They felt they needed to observe the patient, that he be placed in outpatient status and observed. However because he was admitted and discharged before condition code 44 could be carried out the admission must be
Four of five senior tennis players are new to the sport this year. Shaun Petrovich, Matt Larsen, Dylan Ion and Grant Anderson all decided to join the tennis team for their senior year.
Keep track of how many times you can hit it back and forth without it hitting the ground.
After reading "Dear Dads: Save Your Sons" by Christopher N. Bacorn. I started to think about kids in todays society growing up without fathers. It's sad knowing that children without dads turn to drugs and violence. Just like the boy in the fifteen year old boy in the story. His father left four years ago, and the boy turned to alcohol, gangs, failing school and violence.
Every second, the velocity decreases by 10 m/s. " After 2 s, the ball has reached its highest point. # Its velocity changes direction, from upward to downward, passing through a value of 0 m/s. " Now, the downward acceleration increases the downward velocity. What is the ball’s acceleration at the top of its
The distance the shot put can travel (its range) is a function of horizontal velocity and flight time (Lanka, 2000). Release velocity is dependent of the magnitude and direction of forces as well as the distance over which the forces are applied and the duration of the activity (Zatsiorsky, Lanka & Shalmanov, 1981). The acceleration of an object is also affected by gravity due to the structures
Remind participants that they are allowed to leave the experiment at anytime. And they confidentiality will be taken into account to protect their identity. 3. Throw the ball and record the measurement you have thrown it with a tape measure, while you are measuring make sure the participants stand a few metres away so they cannot see.
Tennis is the sport normally thought of as being quiet and gentle, hitting a ball back and forth. Like some sports, swimming for example, it has its spectators and everyone must keep quiet and not distract the professional players from attempting to score or win. No one expects to go to a tennis match to hear someone hit a ball and screech out as if they are in the worst pain of their lives over and over again. This loud and annoying screech is also referred to as grunting and can be a distracting interference that many believe should be banned altogether in the sport of tennis.
The first step in this section is, throw the first ball with the right hand to the left, at head height. When this ball reaches its peak, throw the second ball from the left hand to the right at head height. Second, throw the ball from the left hand to the right hand, at head height. When the ball reaches its peak, throw the other ball from the left hand to the right hand, at head height. The third step I, throw the ball from one hand to the other hand like in steps 1 and 2 of this part.
In the end tennis is a game for everyone. I love it and I know you will too. The benefits of playing are colossal; a longer and happier life, friendships that will last forever, and just good fun. Playing tennis is going to help you excel mentally and physically, who doesn't want that! It is never too late to join in on all the great things tennis has to offer. Sign up for a local class or just grab a friend and try it out. I guarantee that you won't regret it, who knows maybe you'll find your passion just like I did two years ago.
Tennis has played an integral role in defining a major aspect of my high school career. I loved playing the sport throughout my childhood, but high school awarded me the opportunity to employ my years of playing and funnel it into a unique experience which allowed me to meet some of my closest friends. After playing varsity tennis my sophomore year, I was honored when my teammates voted me to be a team captain. To me, this was the greatest possible honor and I knew that I would need to work my hardest to provide a source of leadership and strive to improve the quality of our experience as a team. Since my freshman year, we had worn the same tired uniforms from years before, not due to lack of funding, but due to a lack of commitment to solving
he Immense Power Of People’s Beliefs! The two things that lead people’s behaviour are their necessity to escape from pain and the desire to acquire pleasure. Doing this or that, people believe that they will be led to pain or pleasure. They want to move away from pain and move toward the pleasure. You have to take in consideration two things that motivate people to do something: their feelings and their actions that they think will lead them away from pain and toward the pleasure.
