A"swing" ride at a carnival consists of chairs that are swung in a circle by 11.0 m cables attached to a vertical rotating pole, as the drawing shows. suppose the total mass of a chair and its occupant is 283 kg.
(a) determine the tension in the cable attached to the chair.
(b) find the speed of the chair.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
