a projectile is fired from a cliff 100m high with a velocity of 200m/s. If the angle of projection is 20degrees above the horizontal, find the time of flight correct to 2 decimal places and the range of the projectile from the base of the cliff to the nearest metre. (assume g=9.8 metres per second per second)

Can someone please give me the answers to this question. Explanation is not nessecary. i just need to verify my answers. thanx
