A solid disk of mass 1.45 kg and radius 25.0 cm is initially spinning counterclockwise (as viewed from above) at 15.5 revolutions per second on a massless and frictionless bearing. A second disk, of mass 1.05 kg and radius 12.5 cm is initially spinning clockwise about the same axis at 14.2 revolutions per second, is dropped on top of the first disk. Because there is friction between the disks, they quickly reach a common angular speed. What is their final angular speed, in revolutions per second

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
