A force of 250 and is used to keep up 65 kg crate sliding across the warehouse floor what is the coefficient of sliding friction for the crate in the floor
Consider the following FBD
As seen in the above FBD, the crate moves along the positive X-direction with velocity
The forces on the crates are
is the force due to the friction
is the normal force
is the given applied force to keep the crate sliding
is the weight
From Newton's 2nd law, writing the forces in it's components
From eq.(1), we get
