Question
. Johnny Manziel has decided that he’s a terrible quarterback (he’s pretty mad about it) and
wants to become a kicker, but he’s concerned about the shoe he has chosen to kick with
and how it will impact the inertia of his leg. The moment of inertia of the lower leg and
foot about an axis through the knee joint is 0.20 kg·m2. What is the moment of inertia of
the leg and foot about the knee joint if a 0.50 kg shoe is worn on the foot? Assume that
the shoe’s mass is all concentrated in one point 45 cm from the knee joint.
0.30 kg·m2
