A solid, uniform, frictionless cylindrical reel of mass M=3.00 kg and radius R=0.400 m is used to draw water from a well. The bucket has a mass of 2.00 kg. The bucket is attached to a cord that is wrapped around the reel many times. a. Find the tension T in the cord and acceleration a of the bucket. b. If the bucket starts from rest at the top of the well and falls for 3.00 s before hitting the water, haw far does it fall?
