- A solid cylinder with a mass of 15 kg and a radius of 5 cm is mounted on a frictionless horizontal axle over a well as shown in the Figure below. A rope of negligible mass is wrapped around the cylinder and supports a bucket with a mass of 3 kg. Find the bucket’s acceleration as it falls down the well shaft.) The distance between the centers of the wheels of a motorcycle is 155 cm. The center of mass of the motorcycle, including the rider, is 88.0 cm above the ground and halfway between the wheels. Assume the mass of each wheel is small compared with the body of the motorcycle. The engine drives the rear wheel only. What horizontal acceleration of the motorcycle will make the front wheel rise off the ground? (There are a number of views on how to do this online, if you have difficulty with this problem look them up. One view is to calculate the torque about the point of contact on the ground and also the around the center of mass and set them equal to each other.)
