1. The problem statement, all variables and given/known data A rifle bullet is fired at an angle of 30 degrees below the horizontal with an initial velocity of 800 m/s from the top of a cliff 80 m high. How far from the base of the cliff does it strike the level of ground below g=9.8 initial velocity- 800 m/s y=80 m 2. Relevant equations People i ask say.. R=(initial velocity squared x sin(2 theta) g 3. The attempt at a solution i did 800^2 x sin2(30) 9.8 i get 56556.76106-which seems way to high Then i did Soh Cah Toa Sin=Opp/Adj 56556.76106/80 and got 706.9595133 I really just dont understand what i am doing, and need help. bad. this is due tomorrow.
