Question

Calculate the velocity of a mass 0.5kg,when it has a linear momentum of 5 Ns

Answer 1

momentum = 5Ns 
mass = 0.5 kg
velocity, v=?

we know, p = mv
⇒ 5 = 0.5 × v
⇒ v = 5 / 0.5 = 10 m/s 

velocity = 10 m/s

Answer 2

MASS= 0.5 KG
MOMENTUM= 5Ns
VELOCITY=?
MOMENTUM = MASS * VELOCITY
5 = 0.5 * VELOCITY
VELOCITY = 5/0.5
VELOCITY = 10 M/S
