Question1

A potter's wheel having a radius 0.53 m and a moment of inertia 14 kg•m2 is rotating freely at 53 rev/min. The potter can stop wheel in 6.0 s by pressing a wet rag against the rim and exerting a radically inward force of 74 N. Find out the effective coefficient of kinetic friction between the wheel and the wet rag.

Question2

An Atwood's machine consists of blocks of masses m1 = 11.0 kg and m2 = 17.0 kg attached by a cord running over a pulley. The pulley is a solid cylinder with mass M = 7.90 kg and radius r = 0.200 m. The block of mass m2 is allowed to drop, and the cord turns pulley without slipping.

Question3

A Navy jet of mass 10 kg lands on an aircraft carrier and snags a cable to slow it down. If cable acts like a spring that has a spring constant of 160 N/m and aircraft is stopped by this spring in 25 m after hooking onto the cable, what is the speed of a jet while it first hooks on to the cable (imagine the jet does no breaking on its own)?
