1.	A stone is thrown horizontally with the velocity u=15m/s from a cover of height H=25m. Find (i) the time during which the stone is in motion, (ii) the distance from the tower base to the point where the stone will touch the ground (iii) the velocity v with which it will touch the ground and (iv) the angle theta the trajectory of the stone makes with the horizontal at the point stone touches the ground (Air resistance is to be neglected). (g=10ms^(-2))
Answer» ANSWER :(i) `2.26s` (II) 33.88m (iii) `27.04ms^(-1)` (IV) `56^(@)`
