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

Solutions

Expert Solution

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
