Max (15 kg) pushes Maya (12 kg) on a swing so that Maya moves in simple harmonic motion. The swing is 1.8 meters long and has a mass of 4 kg, concentrated in the seat. If Maya and the swing form a simple pendulum, what is the period of Maya's motion?
On Earth, you swing a simple pendulum in simple harmonic motion with a period of 1.6 seconds. What is the period of this same pendulum on the Moon? Assume the Moon's acceleration due to gravity is 1/6 of the acceleration due to gravity on Earth.
A baseball bat is 32 inches (81.3 cm) long and has a mass of 0.96 kg. Its center of mass is 22 inches (55.9 cm) from the handle end. You hold the bat at the very tip of the handle end (the knob) and let it swing in simple harmonic motion. What is the bat's moment of inertia if its period of oscillation is 1.35 seconds?
