A 39.7-kg crate rests on a horizontal floor, and a 65.3-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.

Answer 1

Floor pushes up total weight
= (39.7 + 65.3)(9.81)

crate pushes up on person
= (65.3)(9.81)
