1. A 60.0 kg fisherman is standing still on a frictionless ice surface when he throws a 3.25 kg fish at 4.00 m/s. With what velocity does the fisherman move across the ice in the opposite direction?
2. A 2.34 kg hammer is dropped from 5.67 m (which is 18.6 feet) above the ground. Using energy considerations only, what is the velocity of the hammer just as it hits the ground?
3. What is the kinetic energy of a 29.5 kg electric bike with a velocity of 32.1 km/h?
