A box of mass mis held on top of an inclined plane of height h. Friction between the inclined plane and the box is negligible.

The box slides down the plane until it reaches ground level with a speed of vms. It continues sliding
along the ground, which has a coefficient of friction of y, until it comes to a complete stop after a distance of s metres.

What is the correct expression for the coefficient of friction?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
