John is pushing a 50 kg box with a force of 100 N. The maximum static frictional force is 125 N. a) Draw a free body diagram. b) What is the coefficient of friction between the box and ground?
Suppose John then pushes the box with Sally on top of it, who is 80 kg. The box comes to a stop and Sally then holds a present of an unknown mass. The maximum static frictional force is found to be 450 N in this system. c) Draw a free body diagram. d) What is the new normal force? e) Determine the total mass of the box+person+present system? f) What is the mass of the present?

John is pushing an 50 kg box. Fs max is found to be 125 N and the normal force is 490 N. The coefficient of static friction is 0.255. Say that while John is pushing the box, Sally who you happen to know is 80 kg sits on top of the box. The new normal force is found to be 1274 N. Sally then holds a present of an unknown mass and the new Fs max is 450 and coefficient...

a student pulls a box of books on a horizontal floor with a force of 100 N in a direction of 37.0 degrees above the horizontal. if the mass of the box and the books is 40.0 kg and the coefficient of static friction between the crate and the dock is 0.55, what is the maximum force of friction? (Will the box move?) Show the free body diagram. (183, 167, 332 or 350 N)
