A box slides up an incline, comes to rest, and then slides down again, accelerating in both directions. Answer the following questions, using only a free-body diagram and without doing any calculations: (a) If there is no friction on the incline, how will the box's acceleration going up compare in magnitude and direction with its acceleration going down? (b) If there is kinetic friction on the incline, how will the box's acceleration going up compare in magnitude and direction with its acceleration going down? (c) What will be the box's acceleration at its highest point?

Two thieves want to steal a 1mx1mx1m Lazada Mystery Box worth of 1million pesos that is placed on a warehouse with a cemented floor. When they successfully break into the warehouse using a bobby pin they realize that they both cannot carry the 400 lb package, so they decided to push it out of the warehouse. If the untouched package and the cemented floor has a coefficient of friction of 0.400, what is the maximum amount of force they first need to exert in order to make the package move when they will: A) push the package with their hands 90 degree with the vertical wall of the box. B) push the package with their hands in 120 degree with the vertical wall of the package. C) When they decided to pull the box instead and their hands are in 120 degree with the top edge of the box.

A box of bananas weighing 40.0 NN rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.40 and the coefficient of kinetic friction is 0.20.
If no horizontal force is applied to the box and the box is at rest, how large is the friction force exerted on the box?
My question, what is the equation to solve for the force of friction? what affect do the kinetic and static friction have on this?
What is the maximum horizontal force that is required to cause a 15kg box to begin to slide along a horizontal surface if the coefficient of static friction is 0.20?
