Question

A toy car of mass 250 g is moving with a velocity of 5m/s.What is its momentum?

Answer 1

Momentum p = mv
m= 250 grams = 0.25 kg
velocity v = 5 m/s
momentum is 0.25*5 which is 1.25 kg m/s

Answer 2

mass(m)=250 g = 250/1000 kg= 0.25 kg
velocity(v)=5 m/s
By using, p=mv
momentum(p)=0.25*5 kg m/s
Therefore, p=1.25 kg m/s
