Temperature Change in a Block By Friction?
uda880: A block of mass m is initially sliding on a frictionless surface at a velocity v(initial), and then hits a strip of sandpaper that has a coefficient of kinetic friction (KF), and has a width of L. After passing the sandpaper, the block continues its journey once again on the frictionless surface. [...]
