Two circular disks each with moment of inertia 11 and 12 are equal mass m are rotating about a horizontal frictionless axle through their centers with angular velocities w1 and w2.if the 2nd disk slip to the left and attached to the 1st one
find (a) The angular velocity after the attachment
(b)the ratio of the rational final KE to the initial KE

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
