Q1. A mass of 0.162 kg is attached to a wheel by a string wrapped around the wheel. The wheel has a mass of 1.98 kg. Assume that the moment of inertia of the wheel is the same as a disk.

Find the acceleration of mass. (Up is positive, and down is negative.)

Q2. A toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with a constant speed of 1.03m/s in a horizontal circle. If the angle the string makes with the vertical is 27°, and the tension of the string is 1N.
