A car starts from rest and accelerates uniformly over the time of 0.21 – InterviewSolution

1.

A car starts from rest and accelerates uniformly over the time of 0.21 s for a distance of 110 m . determine the acceleration of car

Answer»

Explanation:

Initial VELOCITY(u)= 0m/s. [Because it is in rest]

Time taken to accelerate= 0.21s

Distance covered= 110m

Using second equation of MOTION =>

s = ut + ½ at²

As, u = 0

=> a = 2s/t²

=> a = (2*110)

/(0.21)² [By putting the VALUE
