If a baseball is batted at an angle of 35° to
the ground, the distance the ball travels
can be estimated using the equation
d = 0.0034s2 + 0.004s – 0.3, where s is the
bat speed, in kilometres per hour, and d is
the distance flown, in metres. at what speed
does the batter need to hit the ball in order
to have a home run where the ball-flies
125 m? round to the nearest tenth.
