I just need help with part c. I know stopping takes longer but we have to explain why.

A student stands on a bathroom scale in an elevator at rest on the 64th floor of a building. The scale reads 849 N.

(a) As the elevator moves up, the scale reading increases to 912 N. Find the acceleration of the elevator.

0.73 m/s^2

(b) As the elevator approaches the 74th floor, the scale reading drops to 782 N. What is the acceleration of the elevator?

-0.77 m/s^2

(c) Using your results from parts a and b, select which change in velocity, starting or stopping, takes the longer time.
