Question

A disk with a moment of inertia I is rotating with an angular velocity of w when a small lump of clay drops onto the edge of the disk. The angular velocity of the disk will:

a. Increase because the falling clay strikes the disk with initial kinetic energy which will be given to the disk, increasing its rotational speed

b. Decrease because the lump of clay with no initial angular velocity makes an inelastic collision with the disk causing the composite mass to slow

c. Remain constant since the mass of the disk is much larger than the lump of clay

d. Increase immediately as the small lump of clay makes contact with the disk but will decrease over time as the lump of clay spreads out on the disk.

Answer 1

sorry bro, but I don't think so that I am able to gave you the best answer for it . sorry
