Question

the brakes applied to a car produce an acceleration of 6 metre per second square in the opposite direction to the motion if the car takes 3 sec to come to rest after the application of brakes calculate (a) initial velocity (b) distance covered by the car before stopping​

Answer 1

Answer:I will try my best to explain mark me the brainliest

Explanation:

Acceleration =6m/s2

Time=3 sec

Final velocity =0( coming to rest)

a) yo find initial velocity

By 1st equation of motion

V=u+at

0=u+6*3

0=u+18

-18 =u

b) to find distance

S=ut +1/2at2

S =18*3+1/2*6*3*3

S=54+3*9

S=72 m

Your welcome

I think. It’s correct

Good luck
