Question

A car is moving at the velocity of 25 m/s The driver applies break to stop it in 5 seconds Find the acceleration of the car

Answer 1

Explanation:

u=25m/s

t=5sec

v=0m/s

a=v-u/t

=-25/5

=-5m/s^2

Answer 2

Answer:

Initial Velocity = 0 m/s

Final Velocity = 25 m/s

Time = 5 seconds

Acceleration = Final velocity - Initial Velocity/ Time

Acceleration = 25 - 0 / 5 = 25 / 5 = 5 m s^-2
