Explanation:
(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
We calculate the total moment of inertia of the rod-ball system after the collision by adding the moment of inertia of the rod and the added contribution from the putty ball. With this, we find the post-collision angular speed using Conservation of Angular Momentum. The rotational kinetic energy is then determined from this angular speed.
To solve this problem, we first need to calculate the moment of inertia of the combined system of the rod and the putty. The moment of inertia of an object is given by its mass times the square of its distance from the axis of rotation. That gives us I = 1/3 ML2 + m(D + L/2)2
Next we use Conservation of Angular Momentum to find the post-collision angular speed (ω). The initial momentum (mVD) is equal to the final moment of inertia times the final angular speed, so ω = mVD / I.
Finally, we calculate the rotational kinetic energy, which is given by ½ I ω2.
