The figure below shows a velocity as a function of time (v version t) graph for a cart moving along a one dimensional track. The position of the cart is measured with a motion director just as in our activity.

Solution

For acceleration to be constant, the slope of the v-t curve must be constant.

For non zero slope, the slope mut be a straight line incline with the the x-axis with some angle

So, the potions where this occurs are:

A-B ,

B-C,

D-E,

E-F

So, answer is all except C-D
