Question

an object of mass 5kg is moving with a velocity 4m/s a constant force of 20N acts on the object what will be the velocity after 3sec?

Answer 1

a = F/m
= 20 / 5
= 4 m/s^2

v = u + at
= 4 + 4*3
= 16 m/s

Velocity after 3s is 16 m/s

Answer 2

A= 20 / 5
= 4 m/s2
v elocity= 4 + 4*3
= 16 m/s
