What do the values of mu s and mu k depend upon? A 0.5-kg block is moving at constant speed on a horizontal surface. The friction force acting on the block is 2N, calculate mu k. Show all the equations. If experimental data is normally distributed what percentage fits within (mean delta m) which is a stand.dev.? What percentage of data that fits within (mean 2delta m)? In order for the force sensor to operate properly, what needs to be done before taking any measurements? What information is presented by the Friction vs Applied force graph on AB, BC regions and at point B.

Explanation / Answer

1) u_s and u_k depend on the strength of the intermolecular forces between the surfaces of the objects which are in contact.

2) 0.5*9.8*u = 2, Solve for u, u = 0.408

3) 68% of the data is within 1 standard deviation, 95% is within 2 standard deviaitons.

4) The force sensor must be "zeroed." No force must be applied and it must be then instructed to assign that force with a value of 0.

5)

AB, force on object increasing, but static fricitonal force opposing force on objects so it does not move.

BC, force exceeds maximum frictional force and the object begins to move, since it is moving only kinetic friction acts wthich has a lesser value than the static friction so the frictional force decreases
