Question
Problem 7: A block of mass m = 2.5 kg is attached to a spring with spring constant k =
980 N/m. It is initially at rest on an inclined plane that is at an angle of 0 = 25° with respect to the
horizontal, and the coefficient of kinetic friction between the block and the plane is u = 0.13. In the
initial position, where the spring is compressed by a distance of d = 0.15 m, the mass is at its lowest
position and the spring is compressed the maximum amount. Take the initial gravitational energy of
the block as zero.
