Two figure skaters, one weighing 675 N and the other 750 N, push off against each other on very smooth ice.
1. If the heavier skater travels at 1.20 m/s, how fast will the lighter one travel?
2. How much kinetic energy is "created" during the skaters' maneuver?
3. Where does this energy...
A catcher catches a 145g baseball traveling horizontally at 34.0 m/s
1. How large an impulse does the ball give to the catcher?
2. If it takes the ball 23.0ms to stop once it is in contact with the catcher's glove, what average force did the ball exert on the catcher?
is this right...
