14. 1. Calculate the acceleration of a moving car whose speed changes from 7 m/s to 12 m/s
during 2.5 sec.

Acceleration (magnitude) = (change in speed) / (time for the change)

Change in speed = (end speed) - (start speed)

Change in speed = (12 m/s) - (7 m/s)

Change in speed = 5 m/s

Acceleration = (5 m/s) / (2.5 s)

Acceleration = 2 m/s²
