    Maximum KE of 20 kg block with spring (k=2.0 kN/m) and friction

    Got it! Thanks for both of your help! 3.6 J is the final answer. I used the work-energy theorem and took the derivative AND set it to zero, find x. Then plug the x back into solve for KE. Thank you for your advice. Merry Christmas!

    Ok I see, thanks for the words!

    Maximum KE of 20 kg block with spring (k=2.0 kN/m) and friction

    I know what you mean. But how would you solve it if you were to not equate the two forces?

    Maximum KE of 20 kg block with spring (k=2.0 kN/m) and friction

    Homework Statement A 20.0 kg block on a horizontal surface is attached to a horizontal spring of k = 2.0 kN/m. The block is pulled to the right so that the spring is extended 10.0 cm beyond its unstretched length, and the block is then released from rest. The frictional force between the...
