Q1. While a roofer is working on a roof that slants at 44.0 above the horizontal, he accidentally nudges his 93.0 toolbox, causing it to start sliding downward, starting from rest.

Q2. Two balls, of masses m_A = 44 {rm g} and m_B = 61 {rm g}, are suspended. The lighter ball is pulled away to a 66 ^circ angle with the vertical and released. Assume that the positive x axis is fixed to the right.

Q3. A potter's wheel having a radius 0.55 m and a moment of inertia 13.8 kg•m2 is rotating freely at 50 rev/min. The potter can stop the wheel in 4.5 s by pressing a wet rag against rim and exerting a radially inward force of 69 N. Find out an effective coefficient of kinetic friction between the wheel and the wet rag.
