PART Two N CHECKING CONCEPTS PART ONE CHECKING CONCEPTS 1. The SI unit of force is the 2. To measure work, you must know both force and 3. Work can be measured in newton- 1. Workforce X 2. Work is not done unless something is 3. The ability to do work is 4. For work to be done, the direction of the must be the same as the direction of motion. 1. The SI unit of work is the 5. One joule is equal to 1 6. To measure work, you must know the amount of force applied in the direction of​

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.)
