Q1. A steel ball of mass M is released from rest at point P. It follows a smooth curved rail to point Q and finally reaches point R with K.E. of 7J. The speed of the ball at point Q is 2MS-1 and the height between point P and the ground is 3m. Then find the value of M and the height of point Q.

Q2. River Pascal with the volume flow rate of 5.0×10^5 joins with River Archimedes, that carries 1.09×10^6, to form the Bernoulli River. The Bernoulli River is 150 wide and 60 deep. What is the speed of the water in Bernoulli River?
