What is the linear momentum of a car of mass 1,000 kg that is moving at a speed of 20 m/s? what is the momentum of a truck of mass 5,000 kg moving at the same speed?

Explanation

The magnitude of the car's linear momentum is
`P_(car)m_(car)v=(1,000kg)(20m//s)=20,000kg*m//s`.
whole magnitude of the truck's linear momentum
`P_("truck")=m_("truck")v=(5,000kg)(20m//s)=100,000kg*m//s`.
Although the car and truck have the same speed, the truck has more momentum because it has more mass.
