... is momentum? A) the bug B) the car C) both the same ____ 5) The momentum of a punch is changed by a fighter’s jaw. The fighter receiving the punch “rolls with the punch” so as to: A) increases the time of contact, and therefore decrease the average force of the punch B) decrease the time of contact, ...

... a velocity of 0.28 m/s [R]. What is the final velocity of the first ball? 2. An ivory ball of mass 100 g is moving at a velocity of 20 cm/s to the right. It collides with a second ball with a mass of 200 g, which is moving at 10 cm/s to the right. After the collision, the first ball is slowed to 5 c ...

P2a Forces and Their Effects
... Car safety: The force on a passenger will be large if there is a large change in momentum in a short time. The key to safety is to extend the time of impact to reduce the force. This is done by: seat belts stretch a little, crumple zones at the front and rear, air bags to cushion the impact. ...

... device to measure projectile velocity v by observing the maximum angle θ to which the box of sand with embedded projectile swings. Calculate the angle θ if the 2-oz projectile is fired horizontally into the suspended 50-lb box of sand with a velocity v = 2000 ft/sec. Also find the percentage of ener ...

Momentum and Its Conservation
... A 2.00-kg ball, A, is moving at a speed of 5.00 m/s. It collides with a stationary ball, B, of the same mass. After the collision, A moves off in a direction 30.0º to the left of its original direction. Ball B moves off in a direction 90.0º to the right of ball A's final direction. How fast are they ...
