Question
A baseball bat has a "sweet spot" where a ball can be hit
with almost effortless transmission of energy. A careful
analysis of baseball dynamics shows that this special
spot is located at the point where an applied force would
result in pure rotation of the bat about the handle grip.
Part A
Determine the location of the sweet spot of the bat shown in the figure (Figure 1). The linear mass
density of the bat is given roughly by (0.61+3.3x²) kg/m, where æ is in meters measured from
the end of the handle. The entire bat is 0.83 m long. The desired rotation point should be 5.0 cm
from the end where the bat is held. [Hint. Where is the cm of the bat?]
Express your answer using two significant figures.
