An empty cylindrical barrel is open at one end and rolls without slipping straight down a hill. The barrel has a mass of 23.0 kg, a radius of 0.533 m, and a length of 0.800 m. The mass of the end of the barrel equals a third of the mass of its side, and the thickness of the barrel is negligible. The acceleration due to gravity is =9.80 m/s2. What is the translational speed f of the barrel at the bottom of the hill if released from rest at a height of 21.0 m above the bottom?

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
