Question

the brakes applied to a car produce an acceleration of 6m/s2 in the opposite direction to the motion . if the car takes 2 s to stop after the application of brakes , calculate the distance it travel during this time.​

Answer 1

Answer:

12m

Explanation:

Given:

Accerleration: a=−6 m/s

2

Time t=2 s

Final velocity, v=0 m/s

v=u+at

0=u−6×2

u=12 m/s

s=ut+

at

2

s=12×2+

×(−6)×4

⇒s=12 m
