If a pendulum is oscillating at an angle Φo=60 degree, compute by what percent the period deviates from its small angle limit.
A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
The motion of a very massive object is hardly affected by what would seem to be a substantial force. Consider a supertanker, with a mass of 2.7×10^8 kg. find what will be the magnitude of its acceleration
A diatomic gas has a volume of 2m^3, pressure of 200 kPa and atemperature of 50 degrees Celsius. The gas expands is obarically toa volume of 3m^3. What is the heat transfer into the gas?

A 2 cm diameter, 5 cm long capillary-tube viscometer is being used to measure viscosity of a 10 Pa s liquid food. Determine the pressure required for measurementhen a flow rate of 1 kg/min
The bugle and the Bach - Trumpet have no keys and thus play only the natural scale (open pipes). If the lowest note you can play on a bugle is D2 (73.42 Hz), what other notes can you play
Find the mechanical energy of a block-spring system having a spring constant of 0.67 N/cm and an oscillation amplitude of 1.5 cm
A man enters a tall tower, needing to know its height. He notes that a long pendulum extends from the ceiling almost to the floor and that its period is 10.0 s. How tall is the tower?
You may also assume that v_0 gg sqrt{2gL}, so that the change in hammer's gravitational potential energy, as it drives the nail into the block, is insignificant.
