Unformatted text preview: mata (jpm2873) HW #6 Antoniewicz (57420) 1 This print-out should have 21 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 3) 4.0 points Starting from rest, a(n)8 kg block slides 11 . 5 m down a frictionless ramp (inclined at 30 from the floor) to the bottom. The block then slides an additional 25 . 5 m along the floor before coming to stop. The acceleration of gravity is 9 . 8 m / s 2 . 1 1 . 5 m 8 kg 8 k g 30 25 . 5 m Find the speed of the block at the bottom of the ramp. Answer in units of m / s. 002 (part 2 of 3) 3.0 points Find the coefficient of kinetic friction between block and floor. 003 (part 3 of 3) 3.0 points Find the magnitude of the mechanical energy lost due to friction. Answer in units of J. 004 10.0 points The spring has a constant of 27 N / m and the frictional surface is 0 . 2 m long with a coefficient of friction = 1 . 08 . The 6 kg block depresses the spring by 15 cm, then is released. The first drop is 1 . 7 m and the second is 2 m. The acceleration of gravity is 9 . 8 m / s 2 . h h L m k x 1 2 s How far from the bottom of the cliff does it land? Answer in units of m. 005 (part 1 of 2) 5.0 points The two blocks are connected by a light string that passes over a frictionless pulley with a negligible mass. The 5 kg block lies on a rough horizontal surface with a constant coefficient of kinetic friction 0 . 4. This block is connected to a spring with spring constant 5 N / m. The second block has a mass of 8 kg....
