Arod of mass m = 116 g and length l = 49 cm can rotate about a hinge at its left end and is initially at rest. a putty ball of mass m = 14 g, moving with speed v= 6 m/s, strikes the rod at angle a = 37º a distance d=l/4 from the end and sticks to the rod after the collision.
(a) what is the total moment of inertia, 1, with respect to the hinge, of the rod-ball-system after the collision?
(b) enter an expression for the angular speed w of the system immediately after the collision, in terms of m, v, d, 0,
(c) calculate the rotational kinetic energy, in joules, of the system after the collision

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
