Question

A student has assembled an arrangement of tracks on which a steel ball has the motion represented by the v versus t graph at the right. The ball is released from rest (v = 0 cm/s) at x = 46 cm when t = 0 s. 

a. At what time (to the nearest second) was the ball at x = 188 cm? Show your work, explaining how you determined your answer from the v versus t graph.

b. What was the magnitude of the average velocity of the ball over the entire time interval shown on the graph (i.e., between t = 0 s and t = 20 s)? Show all work.

3. A student has assembled an arrangement of tracks on which a steel ball has the motion
represented by the vversus t graph at right. The ball is released from rest (v=0 cm/s)
at x = 46 cm when t=0 s.
