A ball is tossed from an upper story window of a building. The ball is given an initial velocity of 8.0m/s at an angle of 20.0 below the horizontal. It strikes the ground 3.00s later.

a) How far horizontally from the base of the building does the ball strike the ground?

b) Find the height from which the ball was thrown

c)How long does it take the ball to reach a point 10.0 below the landing?

2. Relevant equations

for a. the equation is R=vxit=vicostheta)*2t

for b. h=v^2sin^2thetai/2*g

for c. I think its Rmax

3. The attempt at a solution

ive plugged in the values to the equations but i still dont get the correct answer
