Problem
A small block is released from rest at point A on a smooth track that is 8m above ground level. It slides down to point B, which is 3m above the ground, and then continues to point C at ground level.
(i) Calculate the speed of the block at point B.
(ii) Calculate the speed of the block at point C.
(iii) The block is now given an initial horizontal push of 5ms−1 at A. Recalculate its speeds at B and C.
