The
velocity-time graph on the right displays the behavior of a race
cart along a straight track. Determine the following: (a) the
average acceleration of the cart from t=0.0min to t=40.0min. (b)
the cart’s instantaneous acceleration at t=30.0min. (c) the cart’s
displacement for the entire graph shown on the graph.

Please show all your work.
5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

4. Draw both a position-versus-time graph and a velocity-versus-time graph for an object at rest at x=1m. 5. The figure shows the position-versus-time graphs for two objects, A and B, that are moving along the same axis. At the instant t1 s, is the speed of A greater than, less than, or equa to the speed of B? Explain. b. Do objects A and B ever have the same speed? If so, at what time or times? Explain. 6. Below...
