In a pinball machine, a ball of mass 120 gram is placed in front of a horizontal spring of spring constant k = 90 N/m. The spring is pulled so that it squeezes by x = 5 cm, and then let go. The ball then rises up a ramp. Assume no rotation of the ball, what will be the speed of the ball when it has travelled L = 63 cm along the incline. The ramp is at an angle of θ = 8 degrees. Ignore friction.

A block of mass m = 2.37 kg is attached to a spring with spring constant k = 835 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 28.3∘ with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.15. In the initial position, where the spring is compressed by a distance of d = 0.106 m, the mass is at its lowest position and the spring is compressed the maximum amount. Take the initial gravitational potential energy of the block as zero.

A block of mass m = 3.37 kg is attached to a spring with spring constant k = 785 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 28.3∘ with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. In the initial position, where the spring is compressed by a distance of d = 0.151 m, the mass is at its lowest position and the spring is compressed the maximum amount. Take the initial gravitational potential energy of the block as zero.

A block of mass m = 0.1 kg falls down a ramp of height h = 0.5 m and angle θ = 30 degrees. The coefficient of kinetic friction between the block and the ramp is given by μ, which will vary throughout this problem. At the end of the ramp, the block slides along a frictionless horizontal surface until it makes contact with, and compresses, a mass-less spring with spring constant k = 1.0 N/m. Assume g = 9.81 m/s2. Determine the following:Assume the ramp is frictionless (i. e., μ = 0). What is the maximum distance that the spring will compress? What coefficient of kinetic friction, μ, will cause the spring to compress by exactly half the distance that it did when the ramp was frictionless? Using the value of the coefficient of friction found in part 2, when the spring pushes the block back towards the ramp, what is the maximum height that the block reaches?
