A spring with a spring constant of 500 N/m is used to propel a 0.41-kg mass up an inclined plane. The spring is compressed 30 cm from its equilibrium position and launches the mass from rest across a horizontal surface and onto the plane. The plane has a length l = 3 m and is inclined at 36°. 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 at distance d = 1.4 m from the bottom of the plane.
What is the total work done by friction from the beginning to the end of the mass's motion?
