Starting from rest, a(n) 11 kg block slides 14.9 m down a frictionless ramp (inclined at 30 from the floor) to the bottom. The block then slides an additional 14.9 m along the floor before coming to stop. The acceleration of gravity is 9.8 m/s. 111 kg 14.9 m 11 kg 30 14.9 m Find the speed of the block at the bottom of the ramp. Answer in units of m/s. 022 (part 2 of 3) 10.0 points Find the coefficient of kinetic friction between block and floor. 023 (part 3 of 3) 10.0 points Find the magnitude of the mechanical energy lost due to friction. Answer in units of J.
