Question

The brake applied to a car produces an acceleration of 10ms^-2 in the opposite direction to the motion. If the car takes 3s to stop after the application of brakes, Calculate the distance travelled during this time? Plz answer ASAP!! ​

Answer 1

a = 10m/s² t = 3s u = 0

S = ut + 1/2 at²

S = 1/2 10× 9 = 45 m
