A small block of mass m = 35 g can slide along the frictionless loop-the-loop, with loop radius R = 22 cm. The block is released from rest at point P, at height h = 6.0R above the bottom of the loop. If the gravitational potential energy of the block- Earth system is taken to be zero at the bottom of the loop, what is that potential energy when the block is at point Q? (Your result must be in joules and include 3 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m/s?) R
