Question

A car was moving at a rate of 18km/hr when the brakes were applied. if it comes to rest after traveling a distance of 5m calculate the retardation produced in the car​

Answer 1

18kmph=18×5/18m/s=5m/s

v=0

d=5

v^2 + u^2 = 2as

0 - 25 = 2(a)(5)

a= -25/10= -2.5 m/s^2

Answer 2

here is the explaination
