Question

A body is traveling with a velocity 30m/s it is given an acceleration 5m/S2.what will be it's velocity after 4s?

Answer 1

Answer:

v=u+at

v=30+5×4

v=50m/s

Explanation:

I hope it helps you.

Answer 2

Answer:

Here we use the kinematics first equation of motion to find the velocity after 4 seconds

v=u+at

Explanation:

Here , u=30m/s , t=4sec , a=5m/s²

by putting this values in equation v=u+at

we get,

v=30+5×4

v=30+20

v=50m/s
