1) A 0.490 kg soccer ball is kicked and hits a 2.45 kgstationary tether ball hanging from a 1.49 m tether resulting in aperfectly elastic collision. If the tether ball swings out at amaximum angle of 45.4°, what was the soccer ball's velocity beforethe collision?
2) A 5.27 g pellet is shot horizontally from a BB gun at a speed of15.2 m/s into a 21.1 g wooden block. The wooden block is attachedto a spring and lies on a frictionless table. If the collision isinelastic and the spring constant k = 20.0 N/m, what isthe maximum compression of the spring?
