Mechanics: Force, Collision and Conservation of Momentum
Not what you're looking for?
A car (m1) is traveling at a velocity (v1) and it smashes into a wall. In situation 1: the car bounces off in a completely elastic collision with no change in speed. In situation 2: the car stops by inelastic collision. Which situation would be the most dangerous. Why?

One of James bond's adversaries is standing on a frozen lake; there is no friction between his feet and the ice. He throws his steel-lined hat with a velocity of 22.0 m/s at 36.9 Degrees above the horizontal, hoping to hit James. If his mass is 120 kg and that of his hat is 4.50 kg, what is the magnitude of his horizontal recoil velocity?

A car (m1) is traveling at a velocity (v1) and it smashes into a wall. In situation 1: the car bounces off in a completely elastic collision with no change in speed. In situation 2: the car stops by inelastic collision. Which situation would be the most dangerous. Why?
Answer:
The situation one is most dangerous because the change in the linear momentum of the car in situation 1 is (final - initial) = (- ...
