a batter hits a fly ball which leaves the bat 0.88m above the ground at an angle of 62 with an initial speed of 29m/s heading toward centerfield. Ignore air resistance
a) how far from home plate would the ball land if not caught?
b) the ball is caught by the centerfield who, starting, at a distance of 105m from home plate, runs straight toward home plate at a constant speed and makes the catch at ground level. Find his speed.
