Question

4. Bradford hopped into his Ford Mustang GT to rush to Diana and tell her

how fantastic his students did on the End of course exam. His Mustang

can go from 0 to 60 mph in a brief 4.7 seconds. Bradford accelerated to

top speed quickly and then maintained a speed of 60 mph until he

arrived at Diane's office.

Answer 1

See explanation and image attached

Explanation:

Acceleration refers to the rate of change of speed with time. We can see that between 0 and 4.7 seconds he accelerated quickly . That means that the rate of change of speed with time was greatest between 0 and 4.7 seconds.

A graph of the motion is shown in the image attached. We can see that he maintained a constant speed after 4.7 seconds.
