Question

the graph above describes the motion of a ball. at what point is the velocity of the ball equal to its velocity at b?
o d
o none of the above
o a
o c

Explanation:

Step1: Recall velocity - time graph property

In a velocity - time graph, velocity is represented by the y - coordinate. Points with the same y - coordinate have the same velocity.

Step2: Check y - coordinates of points

Point B and point D have the same y - coordinate on the velocity - time graph. So they have the same velocity.

Answer:

D. D
