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 13.0 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 joules)
