Two different disks of radii r₁ > r₂ are free to spin separately about an axis through the center and perpendicular to the plane of each disk. Both disks start from rest, and both undergo the same angular acceleration for the same length of time. Which disk will have the larger final angular velocity?

(A) Disk 1

(B) Disk 2

(C) The disks will have the same angular velocity.

(D) The answer depends on the mass of the disks.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
