1. The problem statement, all variables and given/known data A 2- kg block rests against one end of a horizontal spring which is compressed by 18 cm. When the spring is released, the spring forces the block to slide across a table top. It stops 47 cm from where you released it. The spring constant k is equal to 120 N/m. Calculate the constant of kinetic friction μk between the block and the table. 2. Relevant equations W=.5kx^2 W=Fd 3. The attempt at a solution I used the two equation above to find that F=4.136N Somebody suggested I should put this into the equation F=μk*F(n), but I don't know how to find F(n). Any help?
