Problem 1: A bicycle can be modeled as three parts: the back wheel, the frame, and the front wheel. A. Write the equation for the kinetic energy of the whole bicycle (i.e. the energy of the wheels plus the energy of the frame) in terms of the linear velocity v, the mass of the wheels my and the mass of the frame mɛ. Consider the mass in the wheels to be all concentrated on I the outer edge. B. If the wheels each have a mass of 1.5 kg, and the frame has a mass of 8 kg, How much work would be required to be done on the bicycle in order to get it to a final velocity of 15 m's if it started from rest? C. Compare the amount of work done on the bike from part B with a similar bicycle that has wheels that are 1 kg each and a frame which is 9 kg. How much work would be required to bring this bike to 15 m's? Which bike is easier to ride?

A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as represented in Figure CQ7.5. The bob moves without friction, swinging equally high on both sides. It moves from its turning point A through point B and reaches its maximum speed at point C. (a) At what point does the bob have non-zero radial acceleration and zero tangential acceleration? What is the direction of its total acceleration at this point? (b) At what point does the bob have nonzero tangential acceleration and zero radial acceleration? What is the direction of its total acceleration at this point? (c) At what point does the bob have both nonzero tangential and radial acceleration? What is the direction of its total acceleration at this point? Figure CQ7.5
