Van Hensley · Answer 1

The acceleration of the object is simply calculated by the change in the object velocity final - initial and then divided by the amount of time.

A = v/t = 72 - 54/10 = 18 km/hr

Assuming 10 seconds

18 km/3600 seconds = 0.005 km/sec

0.005 • 1000 = 5m/sec

A = v/t = 5 m/s / 10 s = 0.5 m/s.
