A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 9.30 m/s at an angle of 21.0 below the horizontal. It strikes the ground 5.00 s later.(a) How far horizontally from the base of the building does the ball strike the ground?m(b) Find the height from which the ball was thrown.m(c) How long does it take the ball to reach a point 10.0 m below the level of launching?sIm having trouble with B and C if u guys can explain them I'll appreciate it a lot!

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 9.30 m/s at a (a) How far horizontally from the base of the building does the ball strike the ground? 43.4 or m (b) Find the height from which the ball was thrown. 126.80 X Work only with the vertical components of these quantities. This part of the problem is then a 1-dime (c) How long does it take the ball to reach a point 10.0 m below the level of launching? 0.24 x The answer to this part does not depend on your answers to parts (a) and (b). s
