A driver starts his parked car and within 5 seconds reaches a speed of 60 km / h, as he travel east. what is his acceleration?

Acceleration =

(change in speed) / (time for the change)

AND

(direction of the change)

- - Change in speed = (end value) - (start value) = 60 km/hr

= 16-2/3 m/s

- - Time for the change = 5 sec

- - Direction of the change = east.

Acceleration = 3-1/3 m/s² east.
