Q1. The center of mass of a 0.30 kg (non-uniform) meter stick is located at its 45 cm mark. What is the magnitude of the torque (in Nm) because of gravity if it is supported at the 28 cm mark?

Q2. When Royce was 10 years old, he had a mass of 35 kg. By the time he was 16 years old his mass increased to 65 kg. How much larger is the gravitational force between Royce and Earth at age 16 compared to age 10?

Q3. A flat uniform circular disk (radius = 2.40 m, mass = 1.00 x 10^2 kg) is initially stationary. The disk is free to rotate in the horizontal plane about a frictionless axis perpendicular to the center of the disk. A 45.0 kg person, standing 0.95 m from the axis, begins to run on the disk in a circular path and has a tangential speed of 2.38 m/s relative to the ground.
