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 has an initial kinetic energy K. If the block moves in the opposite direction with one fifth its initial speed, then what is its new kinetic energy? 4/5 K K/25 -K/5 -K/25 None of the above. A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 9 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction u 0,5. Next. it slides...
2) As the block slides down, its potential energy converts into kinetic energy. If its initial velocity is 1.2 m/s (at x = 3 m), determine its velocity, v, at x = 0.8 m. Your answer must include 2 places after the decimal point and the proper unit. Take g = 9.81 m/s2. v = 1 m/s y = 0.25x? k = 5 kN/m buwiel X 3 m

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 =...
