A 1.95 kg block slides with a speed of 0.850 m/s on a frictionless horizontal surface until it encounters a spring with a force constant of 818 N/m . The block comes to rest after compressing the spring 4.15 cm. Part A Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 0 cm. Part B Find the spring potential energy, U, the kinetic energy...

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 =...
