I figured out the first two problems, but I'm having trouble with the friction problem.

for part b, I'm not sure if I should use the mass of the crate, or use the force from part a, or add them together?

oh whoops. 989.8 then it's been a long day :P

oh wait, 9.8x91=891.8

gravity would be 9.8 and normal would be 91

gravity, and the floor pushing back on both

everywhere, our teacher didn't teach us this yet so I have no idea where to even start.

starting the problem and then direction from there requestedA 38 kg crate rests on a horizontal floor, and a 63 kg person is standing on the crate. (a) Determine the magnitude of the normal force that the floor exerts on the crate. (b) Determine the magnitude of the normal force that the...
