Question

John pushes Hector on a plastic toboggan.The free-body diagram is shown.

A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 490 N. The second vector is pointing right, labeled F Subscript t Baseline = 735 N. The third vector is pointing upward, labeled F Subscript N Baseline = 490 N. The fourth vector is pointing left, labeled F Subscript f Baseline = negative 245 N. The up and down vectors are the same length. The right vector is longer than the left vector.

What is the net force acting on Hector and the toboggan?

245 N
735 N
490 N
980 N

Answer 1

Net vertical = 490 N up − 490 N down = 0.
Net horizontal = 735 N right − 245 N left = 490 N right.

So the net force is 490 N (to the right).
