Question

The brakes applied to a car produce an acceleration of 6 metre per second square in the opposite direction of the motion . If the car takes 2 sec to stop after the application of brakes calculate the distance traveled during this time

Answer 1

Acceleration = 6m/s²
Time = 2s
Initial Velocity = 0

s = ut x 1/2at²

s = (0 x 2) x 1/2 x 6m/s² x (2s)²

s = 3m/s² x 4s²

s = 12m

Distance covered = 12m
