If 
is the angle between the path of a moving object and a fixed ray (see the figure below) , the angular velocity of the object is 
and the angular acceleration of the object is 
. 
Suppose a baseball batter rotates a bat through an angle of 
with a constant angular acceleration of 
rad/2s2. If the tip of the bat is located 
feet from the pivot point (the batter's body) , the (linear) speed of the tip of the bat is 
. Find the value of 
that will produce a speed of 
mph for the tip of the bat at impact. Round to the nearest integer.
A) 
rad/s2
B) 
rad/s2
C) 
rad/s2
D) 
rad/s2
