Question

A body o mass 25kg is at rest and a force of 100 newton is applied to it. What will be the velocity after 10 sec?

Answer 1

F=ma
the force(F=100 N) applied to the body
And the body mass is 25 kg so here a=F/m=100/25=4 Metre per second square
From the equation v=u+at
v=4×10 (u=o)
=40 m/s
40 m/s will be the velocity after 10s

Answer 2

a = F / m
= 100 N / 25 kg
= 4 m/s²

v = u + at
= 0 + (4 m/s² × 10 s)
= 40 m/s

Velocity after 10 seconds is 40 m/s
