Question

A projectile is shot at a 37 degree angle from the edge of a cliff h = 305 m above ground level with an initial speed of v0 = 125 m/s
how much time will it take to hit the ground

Answer 1

vertical : velocityinitial Viv=125sin37

hfinal=ho+Viv*t-4.9t^2
ho=0,hf=-125, Viv above, solve for t.
