A blоck with mаss m=[m]-kg is fоrced аgаinst a hоrizontal spring of negligible mass, compressing the spring a distance of x=[x] m. When released, the block moves on a horizontal tabletop for d=[d] m before coming to rest. The spring constant is [k] N/m. What is the coefficient of friction between the block and the tabletop? (Hint: Use energy conservation). (Show work, +15). Follow these steps: a) What is the work done by the friction during this process (that's Wother)? b) What is the initial energy stored in the spring (i.e. elastic Potential Energy)? c) Use K1+U1+Wother = K2+U2. Write expressions for each of these quantities. d) Solve the above equation to find the the coefficient of friction. Enter the value of the coefficient of friction, rounded off to TWO decimal places:
