Question

a body moving with speed 15m/s is accelerated by 5m/s^2 .find its speed after 3 sec​

Answer 1

Given

A body

have ACCELERATION:-5m/s²

initial velocity=25m/s

To find

velocity of body at t =3sec

Solution

From Equation of motion

V=u+at

V=25+5×3

V=40m/s

Hence the speed of the car after 3sec is 40m/s..
