A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.2-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.2-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.22. Part C How far is the spring compressed? Express your answer...

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 =...
On a planet having g= 10m/s^2, a 2kg mass, starting from rest, slides down a frictionless in life on to a frictionless horizontal surface. The speed of the mass on the horizontal surface is 10m/s. A) Determine the height h at which the box began its slide. consider again the same frictionless incline. However, upon reaching the horizontal surface, a surface having friction is encountered. B) If when the mass starts from the same height as in part A), the...
