A dogsled team is shown pulling a man on a sled. Below the picture is a free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 50 N. The second vector is pointing left, labeled F Subscript f Baseline = negative 225 N. The third vector is pointing upward, labeled F Subscript N Baseline = 50 N. The fourth vector is pointing right, labeled F Subscript t Baseline = 225 N. The up and down vectors are the same length. The right and left vectors are the same length.
Using the free-body diagram, calculate the net force acting on the sled. Is the sled in a state of dynamic equilibrium?
