Sammy is doing a strength testing session on the turf in preparation for the upcoming basketball season.  Sammy's mass is 55 kg and she is trying to push a 105 kg sled across the artificial turf outside on Raymond Field.  The coefficient of static friction between the sled and the turf is 0.3.  If Sammy pushes only horizontally against the sled, how much force must she push with to just initiate movement of the sled? (hint: be sure to follow the steps outlined for free body diagrams, including drawing the free body diagram with all forces, force equations in the X and Y direction, and a coordinate system)

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
