Question

A spring with a spring constant of 500 N/m is used to propel a 0.50 kg mass up an inclined plane. The spring is compressed 30 cm from its equilibrium position and lunches the mass from rest across a horizontal surface and onto the inclined plane. The plan has a length of 4 m and h inclined at 30 degree. Both the plane and the horizontal surface have a coefficient of kinetic friction with the mass of 0.35. When the spring is compressed, the mass is 1.5 m from the bottom of the plane. What is the speed of the mass as it reaches the bottom of the plane What is the speed of the mass as it reaches the top inclined plane? What is the total work done by the friction force from the beginning to the end of the mass's motion?
