Asolid brass cylinder and a solid wood cylinder have the same radius and mass (the wood cylinder is longer). released together from rest, they roll down an incline. (a) which cylinder reaches the bottom first, or do they tie? (b) the wood cylinder is then shortened to match the length of the brass cylinder, and the brass cylinder is drilled out along its long (central) axis to match the mass of the wood cylinder. which cylinder now wins the race, or do they tie?
