A girl throws a tennis ball with an initial speed of 20.0 m/s in the direction of 65.0° above the horizontal. She runs after the ball 0.30 s later from rest with a constant acceleration and then catches the ball at the same height. Ignore air resistance. (a) What is the maximum height (measured from the starting point) that the ball attains? (b) How long does it take for the girl (including the initial 0.30 s) to catch the ball? (c) How far has the ball gone horizontally when it is caught? (d) What is the acceleration of the girl during her run?
