A ball is thrown from the brink of a cliff 10 m high with an initial velocity of v0 = 4 m/s at an angle q0 = 31° above the horizontal.
a) How long does it take to land?
I did 4sin(31)-.5(-9.8)t^2, but that is not the right answer.
b) How far from the base of the cliff does it land?
I might be able to solve this one if I knew the time from part a. Can I just use d=vit + 0.5at^2?
c) What is its maximum height above the base of the cliff?
I don't know what to do for this one.
