10 11 12 3. The plot above shows the position vs. clock reading of a body. Label the axes accordingly. Then label the following regions of the graph. a. When is the body traveling in the positive direction? (Label those segments "Positive velocity.") b. When is the body traveling in the negative direction? (Label those segments "Negative velocity.") c. When is the body at rest? (Label those segments or points "Rest.") d. When is the body undergoing zero acceleration? (Label those segments "UM.") e. When is the body speeding up? (Label those segments "Speeding Up.") f. When is the body slowing down? (Label those segments "Slowing Down.") 8. When is the body accelerating while also at rest? Draw a star on any such point/s.

Which of these is an example of high accuracy? a.) An archer hits the bulls-eye b.) An archer hits the same spot on the target three times in a row c.) A student repeatedly calculates the mass of an object to be 49 grams, when the true mass is 52 grams d.) A student throws three pencils into the trash can, but misses and hits the window each time e.) A student calculates the acceleration due to gravity to be 2ms2using three different methods

1. What is the speed of the candy right before the string is cut? 2. After the string is cut, how long does the candy travel for? 3. After the string is cut, how far does the candy travel in the horizontal direction?

A basketball rolls away from you with a constant speed until hit hits a large bump at the end of your driveway. The ball rolls up the bump only under the influence of gravity, then stops for a split second, then rolls down the other side of the bump. [motion away from you is positive motion). Which veloctiy vs. time graph best shows the motion of the ball as it rolls? a. V O b. v O c. v O d. v e. v

Hello, for this question I need what principles in physics that apply to "a person sliding down a playground slide". Like what it relates to this scenario. The playground slide isn't long or anything beyond normal. It's a standard slide.

Draw a picture of a cart rolling up a ramp.  Draw arrows above the cart to show the direction of the velocity and the direction of the acceleration.  Choose a coordinate system and include this in your picture. Draw a new picture of a cart rolling down a ramp.  Draw arrows above the cart to show the direction of the velocity and the direction of the acceleration.  Label your coordinate system. Sketch a graph of the instantaneous acceleration vs. time for the entire motion of the cart as it rolls up and then back down the track after an initial push.  Label the instant where the cart reverses its motion near the top of the track.  Explain your reasoning.  Write down the equation(s) that best represents this graph.  If there are constants in your equation, what kinematic quantities do they represent?  How would you determine these constants from your graph?

I’m really just not sure how to type this into my calculator or even attempt to answer this question.

A ball is thrown at an initial height of 90 feet at an initial velocity of 55 feet/second at an angle of 75 degrees. Given the parametric equations y = 16t2 + Vo · Sin(0)t + ho and r = Vo Cos(0)t. When doing calculations, carry 5 digits of accuracy, so your round off does not build up. a. What is the ball's height in 3 seconds? feet. b. When will the object hit the ground? seconds. c. How far horizontally will the ball be when it hits the ground? feet. d. When will the ball be at its maximum height? seconds. e. What is the ball's maximum height? feet. f. How far horizontally will the ball be when it reaches its maximum height? feet
