Question

A force of 5N acts on a body for 2m/s.Calculate impulse.If the mass of the body is 5g calculate change in velocity

Answer 1

This should be the question:
A force of 5N acts on a body for 2s.Calculate impulse.If the mass of the body is 5g calculate change in velocity

Answer:
F = Impulse / Time
Impulse = F × Time
= 5 × 10
= 50 Ns
Impulse is 50 Ns

Change in velocity = Impulse / Mass
= 50 / (5 × 10^-3)
= 10000 m/s
= 10 km/s
Change in velocity of body is 10 km/s
