Question

two children having a disagreement pull on a 50N sled in opposite directions. one pulls with a force of 300N east, the other with a force of 220N west. a frictional force of 30N exists between the sled and the surface. draw a free body diagram showing all the forces acting on the sled, and determine the net force on the sled

Answer 1

Right ans guys.

50N is the ans.

Answer 2

Since forces are vector quantities, we must indicate direction using positive and negative values. East will be assigned positive and west will be negative. Friction will act as a negative force since it impedes action. To calculate the net force we sum the vector quantities, as follows. Net force equals 50n which is derived by the following calculation: 300n-220n-30n.
