Q1. Laura, whose mass is 35 {rm kg}, jumps horizontally off a 55 {rm kg} canoe at 1.5 {rm m/s} relative to the canoe. What is canoe's speed just after she jumps?

Q2. A potter's wheel having a radius 0.55m and a moment of inertia 12.5 kg·m2 is rotating freely at 55rev/min. The potter can stop the wheel in 6s by pressing a wet rag against the rim and exerting a radially inward force of 68 N.
