A 0.3 kg ball on a rail is rolled down an incline, and then rolls across a table on a horizontal rail. It leaves the rail, and strikes the floor. Assume friction on the rail is negligible. A student finds that it takes 0.055 seconds to pass through a pair of photogates that are 0.183 m apart. The edge of the rail is 1.11 m above the floor. Find the horizontal velocity of the ball as it passes through the photogates. m/s How long does it take to hit the ground after leaving the rail? How far away from the edge of the table should a student place a coin so that the ball would hit the coin? m

A group of dancers decided to have a contest on who’s gonna hit the target precisely. The loser will pay for their dinner. Dancer A fired the ball with a mass of 0.05 kg with an initial velocity 15 m/s at an angle 35° above the x-axis (neglect the air resistance). Find the total time the ball is in the air.
Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
Dr. Liu is learning how to juggle. He tosses a tennis ball (probably bad choice since it is so bouncy) up at 2.0 m/s at a height 1.6 m above the floor and attempts to use the other hand to catch the falling ball. The ball hit the floor at his feet. How long was Dr. Liu's tennis ball in the air (between tossing and landing)? Ignore air drag. He should probably practice tossing his juggling ball at the same height and same speed before attempting to juggle. Hint: You can set the final position to be zero.
Vhas Thed is standing on a bridge. He is at a height 83.6 m above the water below. Suddenly he received a call from his cell phone that makes him mad and throws his phone horizontally off the bridge with a speed of 25.7 m/s. How far does the cell phone travel horizontally before hitting the water? Draw an Illustration.
You need to get into your fourth-floor apartment, but you have forgotten your key to the main ground floor door of the building. You call up to your lazy roommate to come down and let you in, but he says he will throw the keys down to you instead. The window that he throws the keys out of is 13 meters above the ground, and he chucks them with a speed of 2m/s at an angle of 20 degrees above horizontal. The acceleration due to gravity near the surface of earth is 9.8 m/s?. How far back from the window do you need to stand to catch the keys?
A small rocket is launched straight up. When at a height of 5.0km and velocity of 200.0m/s, it releases its booster and enters free fall. Neglecting air friction, what is the velocity of the rocket at a height of 6.0km on its way up? 143m/s 200m/s 244m/s 397m/s
A projectile is fired with an initial velocity of 1000 m/s at an angle of 370 above the horizontal. If air is neglected, the horizontal component of the projectile's velocity after 20 s is: O 16 m/s O 640 m/s O 800 m/s O 600 m/s

A baseball with mass of 0.16 kg is batted into the air. Its initial speed is 35.0 m/s, directed at an angle 39 degrees above the horizontal. If the height of the ball when it was struck by the bat is 35 cm, how high off the ground (in m) is the ball when it reaches the highest point in its trajectory?
The vector position of a 3.50-g particle moving in the xy plane varies in time according to r rightarrow = (3i^ + 3j^ )t + 2j^ t2,where t is in seconds and r rightarrow is in centimeters. At the same time, the vector position of a 5.50-g particle varies asr2 rightarrow = 3i^ - 2i^t2 - 6j^ t. At t = 2.50 s, determine (a) the vector position of the center of mass, (b) the linear momentum of the system, (c) the velocity of the center of mass,(d) the acceleration of the center of mass, and (e) the net force exerted on the two-particle system.
