1. The problem statement, all variables and given/known data A projectile is fired into the air from the top of a 200-m cliff above a valley. It's initial velocity is 60 m/s at 60 degrees above the horizontal. Where does the projectile land? 2. Relevant equations delta x = intial velocity of x * t delta y = -.5*g*t 3. The attempt at a solution I solved for time and got 6.39s. When I put this back in for delta x I get 191.7m. However according to my professor the results should be .41km. Any ideas? Thanks!
