Question: Starting from rest at a height equal to the radius of the circular track, a block of mass 22 kg slides down a quarter

Starting from rest at a height equal to the radius of the circular track, a block of mass 22 kg slides down a quarter circular track under the influence of gravity with friction present (of coefficient ). The radius of the track is 41 m. te The acceleration of gravity is 9.8 m/s. 22 kg 0 41 m If the kinetic energy of the block at the bottom of the track is 6200 J, what is the work done against friction? Answer in units of J.
