1. A potter's wheel of mass 10 kg and radius 30 cm radius can be modelled as a uniform disk. (a) The wheel is spun up from rest to 100 revolutions per minute in a time of 20 seconds. What was the angular acceleration of the wheel? You may assume the wheel rotates in an anti-clockwise sense. (b) The potter now places a lump of clay onto the centre of the wheel. The clay has a mass 2 kg and is in the shape of a solid cylinder of radius 4 cm. The length of the cylinder is parallel with the rotational axis of the potter's wheel. Calculate the new momentum of inertia of the system, which is the sum of the momentum of inertia of the wheel and the the momentum of inertia of the clay, and use this to determine the new angular speed of the wheel and clay system. (c) The potter now applies a constant force of 2 N tangentially to the wheel opposite the direction of its spin. What is the new angular acceleration of the wheel and clay system? (d) If the potter applies this force for a time of 2 seconds, what is the resulting angular Ethe whe12
