A block of mass mm starts from rest and slides down from the top of a wedge of height hh and length dd. The surface of the wedge
forms an angle of \thetaθ with respect to the horizontal direction. The force of kinetic friction between the block and the wedge is \vec{f} f . How fast is the block traveling when it reaches the bottom of the wedge?
Even though all materials are at the same temperature when they come out of the dryer, some like the zipper are far better conductors of heat and can burn you. Cloth is not a good conductor of heat.
