Auniform spherical shell of mass = 4.50 kg and radius = 8.50 cm can rotate about a vertical axis on frictionless bearings. a massless cord passes around the equator of the shell, over a pulley of rotational inertia = 3.00 × 10−3 kg ∙ m2 and radius = 5.00 cm, and is attached to a small object of mass m = 0.600 kg. there is no friction on the pulley’s axle; the cord does not slip on the pulley. what is the speed of the object when it has fallen 82.0 cm after being released from rest? use energy considerations.

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
