Starting from rest at a height equal to the radius of the circular track, a block of mass 24 kg slides down a quarter circular track under the influence of gravity with friction present (of coefficient µ). the radius of the track is 15 m. the acceleration of gravity is 9.8 m/s 2 .starting from rest at a height equal to the radius of the circular track, a block of mass 24 kg slides down a quarter circular track under the influence of gravity with friction present (of coefficient µ). the radius of the track is 15 m. the acceleration of gravity is 9.8 m/s 2 . if the kinetic energy of the block at the
bottom of the track is 3900 j, what is the
work done against friction?
