Physics
An empty cylindrical barrel is open at one end and rolls without slipping straight down a hill. The barrel has a mass of 17. 0 kg, a radius of 0. 280 m, and a length of 0. 700 m. The mass of the end of the barrel equals a fifth of the mass of its side, and the thickness of the barrel is negligible. What is the translational speed f of the barrel at the bottom of the hill if released from rest at a height of 25. 0 m above the bottom?.
