10.5 Exercise 3
A discus thrower rotates with a discus in his hand before letting it go. (a) How does his moment of inertia change after releasing the discus? (b) What would be a good approximation to use in calculating the moment of inertia of the discus thrower and discus?
10.5 Exercise 5
The moment of inertia of a long rod spun around an axis through one end perpendicular to its length is . Why is this moment of inertia greater than it would be if you spun a point mass m at the location of the center of mass of the rod (at L/2) (that would be )?
