Question:The contestant in a circus game must hit a pad with a 5.0 kg mallet to cause a 1.0 kg object to slide up a pole and hit the bell 4.5 m above the pad. What minimum speed must the mallet have as it hits the pad to ring the bell? (Assume that all the kinetic energy of the mallet becomes the gravitational potential energy of the 1.0 kg object.)
