Forces 2. A car of mass 800 kg is towing a trailer of mass 500 kg at a steady speed. Road resistances are estimated at 5 N per kg of mass for each vehicle. a) What is the tractive force of the car? b) If the car and the trailer accelerate at 0.2 what is the new tractive force? What is the extra force necessary to accelerate the vehicles? -2 ms Solution​

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.)

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
