How do you find the net acceleration of an object with known mass, given parallel horizontal forces acting on the object?

It's winter, and you see a friend of yours trying to push a 1000 kg car off of an ice patch. You decide to help out, and try to pull the car out. If your friend applies 50 N of force, and you pull with 150 N of force, then what will the total acceleration of the car be?

Summary

  1. m- mass
  2. kg- kilograms
  3. FPUSH- pushing force
  4. N- newtons
  5. FPULL- pulling force
  6. aNET- net acceleration of the car
  7. m- meters
  8. s- seconds

Notes

    1. FNET- the net force
    2. m- mass
    3. aNET- the net acceleration
    1. aNET- the net acceleration
    1. FNET- the net force
    2. m- mass
    3. aNET- the net acceleration
    1. FNET- the net force
    1. The force-body diagram is just a diagram of the object with all the forces that act on it
    1. FPULL- the pulling force
    2. FPUSH- the pushing force
    3. N- Newtons the units for force
    4. The positive direction is to the right
    1. To add the forces, we add the two parallel force vectors
    1. FPULL- the pulling force
    2. FPUSH- the pushing force
    3. FNET- the net force
    4. N- Newtons
    1. aNET- the net acceleration
    2. N- newtons
    3. kg- kilograms
    1. aNET- the net acceleration
    2. m- meters
    3. s- seconds
