Determine the momentum of 1000-kg car moving northward at 20 m/s.........
A block of mass M slides across a frictionless surface with velocity v until collides with a stationary block of mass m. If the two blocks stick together, what is their velocity after the collision?
(M+m)v / m
(M-m)v
Mv / (M+m)
(M-m)v / M
A car and bird are about to hit each other. Why will the bird suffer more damage?
The bird has smaller mass, and so has bigger change in velocity.
The bird experiences more force
The bird is not moving as fast as the car
The bird changes its momentum more
