Naif Alamri is preparing for his new career on the PGA Tour. He
wants to increase his driving distance by lengthening his driver.
He decides to build a new driver that is identical to his old
driver except for the fact that the new driver is six inches
longer. The masses are the same (0.25 kg) and the moment of inertia
about the center of mass for both drivers is 0.05 kg · m2. The
distance from the axis of rotation to the center of masses is 0.97
m and 1.14 m. Please be neat and show all your work.
a. If the same torque is applied to the swing of each
driver (15 Nm), what are the angular accelerations of each
club?
b. What is the angular velocity of each club at the point
of contact? Assume that both swings move through the same
range of motion from the top of the swing to contact ( = 3/2).
Hint, use an angular variation of one of the
equations of linearly accelerated motion (ωf2 = ωi2 + 2α).
