Question

A car moving initially at 20 m/s accelerates up to 60 m/s during the
course of 5 seconds. The average acceleration of the car is m/s2

Answer 1

Gain in velocity = 60 - 30 = 30 m/s.

Time taken for this gain = 5 seconds

Average acceleration = 30 / 5 = 6 m/s/s.

So, 6 metres per second squared.
