Hi, can someone please give me hints as to how to do this problem? A 12 kg block is released from rest on an 36 degrees inclined plane and moves 2.4m during the next 4.2s. What is the coefficient of kinetic friction for the incline? I know that the normal force = mgcos(delta), and dividing this value from the Fs would give me the coefficient, but how do I find this value? Thank you so much!
