A 40.6-kg crate rests on a horizontal floor, and a 69.1-kg person is standing on the crate. Determine the magnitude of the normal force that (a) the floor exerts on the crate and (b) the crate exerts on the person.
total weight on floor = 9.8*(40.6+69.1) Newtonns which is the force up from the floor on the crate.
for the crate to the person, the person's weight which is 9.8*69.1 Newtons
