Aroldis Chapman throws a baseball towards a batter from a height of 2.3 m, the batter is 17.5m away from the release point. The initial velocity is directed 1.8 degrees below the horizontal.
Ignore air resistance.
(a) What must the initial speed of the ball be if the pitch is to arrive at the batter exactly 1.00 m above the ground?
(b) How long does it take the ball to reach the batter?
(c) If there were no gravity, at what angle would the pitch have to be thrown?

    actually, you are wrong brian. it is 47.34 m/s idiot. wow you are dumb. How could you even get that answer?
