You throw a rock off the cliff at 10 m/s, 200 above the horizontal. The cliff is 25m high. With what angle does it the rock hit the ground?
How long does it take to hit?
4.9t^2 = 200
Now, using that t,
Vy = 9.8t
Vx = 10
so tanθ = 9.8t/10
4.9t^2 = 200
Now, using that t,
Vy = 9.8t
Vx = 10
so tanθ = 9.8t/10
