- A baseball pitcher is attempting to strike out a batter and
they throw their best fast ball at 40m/s. The distance between the
pitchers mound and the center of home plate is 17.5m. The batter
swings the bat at an average of 12 rad/s just 0.3s after the
pitcher releases the ball and the angular displacement of the bat
from the batters shoulder to the hitting position directly over the
place is 1.65 rads.
- Will the bat strike the ball, or will the batter have swung to
early or too late? Justify your answer.
- Assume the batter hits the ball on the sweet spot of the bat
and it was in contact for 0.0007s. If the bat has an instantaneous
velocity of 39.28rad/s when it strikes the ball, and the sweet spot
is 1.25 m away from the axis of rotation, how fast is the sweet
spot moving when they hit the ball?
Will the (0.145kg) ball be able to get to Park’s Green Monster,
which is 310 ft from home plate for a home run? Assume the bat put
a force of 18,436 N on the ball and the resulting flight time of
the ball is 2.4s
