Q1. The pulley system is used to lift a 61 kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. The crate is rising with an acceleration of 2.4 m/s2. Assume the masses of the chains, pulleys, and ropes are negligible, determine the magnitude of force and tension in the upper chain. The tension in the lower chain is .829 kN
Q2. An object with mass3.0 kg is attached to spring with spring stiffness constant and is executing simple harmonic motion. When the object is 0.040 m from its equilibrium position, it is moving with a speed of .55. What is the maximum velocity?
What is the muzzle velocity
What is the angular acceleration
