G Larry , Moe, and Curly are pushing on a 25 kg crate. The crate is sitting on a horizontal floor, and the coefficient of kinetic friction between the floor and the crate is 0.25. Larry pushes to the right with a force of 400 N. Moe pushes to the left with a force of 250 N. Curly pushes straight downward on the crate with a force of 150 N. What is the acceleration of the crate

Explanation:

Given

Mass of crate is

coefficient of kinetic friction

Larry Pushes with a force of to the right

Moe pushes with a force of to the left

Curly Pushes downward with a force of

Net Normal reaction on the ground is

Friction force is given by

Friction Force always opposes the motion

Net Horizontal force on the  box is

acceleration is given by

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
