1. Two blocks are connected by a light string that passes over a frictionless pulley as in the figure. The block of mass 8.24 kg lies on a horizontal surface and is connected to a spring of force constant 335 N/m. The system is released from rest when the spring is unstretched. If the hanging 14.7 kg block falls a distance 0.653 m before coming to rest, calculate the coefficient of kinetic friction between the block m1 and the surface. The acceleration of gravity is 9.8 m/s^2 2. Relevant equations m2gh=m1gμ - 1/2 kx^2 3. The attempt at a solution as the equation says, i just try to solve for the coefficient of friction by substituting the values. am I wrong?
