Question

A car accelerates at a constant rate from zero to 36.8 m/s in 10 seconds and then slows to 13.9 m/s in 5 seconds. What is its average acceleration to the nearest tenth of a m/s2 during the 15 seconds?

Answer 1

Divide the velocity change (13.9 m/s) by the time interval (15 s). That will be the average acceleration.

Answer 2

0.93m/s^2
