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?
While at the county fair, you choose to ride the Ferris wheel. Having eaten too many elephant ears and candy apples, you obtain the motion somewhat unpleasant. Find what is the magnitude of your acceleration
A fountain has jets that squirt water in all directions at a speed of 16 ft/sec from a central point as shown. The dotted curve shows the boundary between the "dry" region (which the fountain doesn't reach) and the "wet" region reached by the wate..
Calculate the work done on 0.205 mol of methane when it is compressed from 10.0 L to 2.25 L at 25 degree's Celsius, assuming that methane is (a) an ideal gas and (b) a van der Waals gas.
