A bus moving along a straight line at 20 m/s undergoes an acceleration of 4 metre per second square.After 2 seconds ,its speed will be:

Answer»

$using \: first \: equation \: of \: motion \: \\ v = u + at$

where

v=final velocity

u=initial velicity

a=acceleration

t=time

v=20+4(2)

v=20+8

final velocity=28m/s
