A stone is throw horizontally with the velocity u 15m/s from a tower of height H = 25 m. 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 (iv) the angle `theta` the trajectory of the stone makes with the horizontal at the point stoen toches the ground (Air resistance is to be neglected). `(g=10ms^(-2))`.

Explanation

(i) 2.26s (ii) 33.88 m , (iii)`27.04 ms^(-1)` , (iv) `56^(@)`
