A block of mass m -2.00 kg collides head on with a block of mass m- 10.0 kg initially at rest on a rough horizontal surface. The block m strikes m2 with a speed of 4.00 m/s. Immediately after the very brief inelastic collision, the 2.00 kg block bounces back with a speed of 1.20 m/s. Ignore the effect of friction during the collision. (a) 4pts.] Calculate the speed of the 10.0 kg block immediately after the collision. (b) 4...

Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a) Draw a free body diagram for the block in the position shown (you do not need to include forces perpendicular...

top of the loop.
After the block slides down the loop from point C to D, it
enters the rough portion of the track. The speed of the block at
point D is the same as point B, and the speed of the block at point
E is half the speed of the block at point D.
