Question

A driver of car travelling at 52 kmph applies brakes and accelerates uniformly in the opposite direction the car stops in 5s what is the distance​

Answer 1

Explanation:

when car starts retarding final velocity V = 0

Given initial velocity u = 52

a =-5

we know

${v }^{2} - {u}^{2} = 2as$

$0 - {52}^{2} = 2( - 5)s$

s = 270.4 km/hr is ur answer
