1. A ball rolls up then down an incline. Sketch an acceleration diagram for the entire motion. 

2. Sketch x versus t, v versus t, and a versus t graphs for the entire motion of a ball rolling up and then down an incline.

a. Use a coordinate system in which the positive x-direction is down the track.

b. Use a coordinate system in which the positive x-direction is up the track.

c. Can an object have a negative acceleration and be speeding up? If so, describe a possible physical situation and a corresponding coordinate system. If not, explain why not.

 

An object that moves along a straight line has the velocity-versus-time graph shown in the figure below. At time t = 0, the object has position x = 0.

a. At time t = 5 s, is the acceleration of the object positive, negative, or zero?

b. At time t = 8 s, is the object speeding up, slowing down, or moving with constant speed?

c. Write an expression for the position of the object as a function of time. 

d. Use your expression from part (c) to determine (if any) at which the object reaches its maximum position.
