Question

If the net force on a 75-N object is 375 N from the left, in what direction will the object move?

Answer 1

suppose the object is at rest on a flat surface. the forces in the vertical direction cancel out (the weight 75N downwards will be 'cancelled' out by the normal force 75N in the opposite direction).

so we should focus on horizontal forces.

there is an applied force from the left. think about pushing an object from the left, where will the object move?
