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
