Why the kinetic frictional force is zero

Reference no: EM1387552

Q. A 1x10^2-kg crate is being pushed across a horizontal floor by a force that makes an angle of 30.0° below the horizontal. The coefficient of kinetic friction is 0.25. What must be the magnitude of, so that the net work completed by it and the kinetic frictional force is zero?
