Question

Which has more momentum, an object with a mass of 5kg moving at 15ms or an object with a mass of 20kg moving at 17ms?

Answer 1

Mass of object 1(m1)= 5kg

Velocity of object 1(v1)= 15m/s

Mass of object 2(m2) = 20 kg

Velocity of object 2(v2)= 17m/s

Momentum of object 1= P1

Momentum of object 2= P2

P1= m1×v1

P1= 5×15 = 75kg m/s

P2= 20×17 = 140kg m/s

So, momentum of object 2 is greater than momentum of object 1.
