Homework Statement
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.20 m/s at an angle of 15.0° below the horizontal. It strikes the ground 3.00 s later.
(a) How far horizontally from the base of the building does the ball strike the ground?
4.90wrong check mark m
(b) Find the height from which the ball was thrown.
wrong check mark m
(c) How long does it take the ball to reach a point 10.0 m below the level of launching?
Homework Equations
i think the equations are r= v^2(sin2theta)/g
h= v^2(sintheta)2/2g
The Attempt at a Solution
i tried pluggin in the values to get how far it traveled and the height..but I am getting it wrong
any help would be appreciated
