Work and Potential Energy on a Sliding Block with Friction A block of weight w s

Question

Work and Potential Energy on a Sliding Block with Friction A block of weight w sits on a plane inclined at an angle theta as shown. (Figure 1) The coefficient of kinetic friction between the plane and the block is mu. Part A What is the work Wf done on the block by the force of friction as the block moves a distance L up the incline? Express your answer in terms of some or all of the following: mu, w, theta, L Part B What is the work W done by the applied force of magnitude F? Express your answer in terms of some or all of the following: mu, w, theta, L Part C What is the charge in the potential energy of the block, delta U, after it has been pushed a distance L up the incline? Express your answer In terms of some or all of the following: mu, w, theta, L Part D This question will be shown after you complete previous question(s).

Explanation / Answer

friction = ?*normalfocrce = ?(wcos?
