A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...

Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...
