Question

A body starts from rest and travels with an acceleration of 1.5 m/s². After t seconds its velocity is 6 m/s . Then t is….? (a) 10 s (b) 5 s (c) 4 s

Answer 1

Given :-

A body starts from rest and travels with an acceleration of 1.5 m/s². After t seconds its velocity is 6 m/s

To Find :-

Time taken

Solution :-

We know that

a = (v - u)/t

t = (v - u)/a

t = (6 - 0)/1.5

t = 6/1.5

t = 60/15

t = 4 s

Hence

Time taken is 4 s
