Asolid disk of mass 2 kg and radius 2 m is given a horizontal push of 20n at a point .3 m above its center. a. what is the minimum μs between the disk and the floor to allow rolling without slipping?

Explanation:

Given:

For the condition of no slip the force of  static friction must be greater than the applied force so that there is no skidding between the contact surfaces at the contact point.

where:

= static frictional force

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
