o) Problem 6: A rod of mass M= 135 g and length L = 38 cm can rotate about a hinge at its end and is initially at rest. A putty ball of mass m = 1/ g, moving with speed V = 8 m/s, strikes rod at angle 0 = 240 a distance D = L/5 from the end and sticks to the rod after the collision. D M m 33% Part (a) What is the total moment of inertia, I, with respect to the hinge, of the rod-ball- tem after the collision? O O ML2 + mD2 ML2 1 = 3 + mD2 I = (M+m)12 12 3 O MJ2 + ml2 3 Submit Hint Feedback I give up! : 3% deduction per hint. Hints remaining: 2 Feedback: 2% deduction per feedback. 33% Part (b) Enter an expression for the angular speed w of the system immediately after the lision, in terms of m, V, D, 0, and I. 33% Part (c) Calculate the rotational kinetic energy, in joules, of the system after the collision
