Transcribed Image Text:

The figure below shows a small spherical ball of mass m rolling down the loop track. The ball is released on the linear portion at a vertical height H from the lowest point. The circular part shown has a radius R. The tangential acceleration of the centre when the ball is at A is (neglect the radius of mass 'm') (a) - H 5 7 m g cos 0 5 (c)--gcose 9 20 R A 5 -- gsi (d)--gsin (b)-. 78 sin 0 The figure below shows a small spherical ball of mass m rolling down the loop track.
