Question

A bus start from rest and then moves with a constant acceleration of 2m/s square. calculate its time of traven if its final velocity is 20 m/s​

Answer 1

Answer:

Its Answer is 10 s.

Explanation:

As acceleration is defined as time rate of change of velocity. So,

a =  $( vf - vi )$ ÷ t

2 = (20 - 0 ) ÷ t

2 =  20 ÷  t

t = 20 ÷ 2

t  = 10 s

We have put initial velocity as zero because  body is starting from rest.

Hope it helps.
