Question

The brakes applied to a car produce an acceleration of 6 m/s2

 in the opposite direction to 

the motion. If the car takes 2s to stop after the application of brakes, calculate the distance 

it travels during this time.​

Answer 1

Answer:

12m

Explanation:

in this,

v=0

t=2 sec

a=-6m/s^2

v=u+at

0=u+(-6)×2

u-12=0

u=12m/s

s=ut+1/2at^2

s=(12×2)+(1/2×-6×2×2)

s=12m

Answer 2

Explanation:

s =12.. happy learning
