1.	A stone is released from rest at the top of a tall tower if the final velocity is 3m /sec find the height of the tower and the time taken to reach the ground
Answer» u MEANS initial velocity is zero because stone in rest v is 3m/sec and ACCELERATION due to gravity is G means 10 then v=u-gt then t is 0.3 sec here g is - g because due to its direction and H= ut-1/2 gt^2 then H= 1/2×10×0.09 then H is 0.45 m
