A block of mass 41.1 kg starts atrest at the top of a frictionless ramp that makes an angle of =27.1 below the horizontal.After it slides without friction down the entire 2.94 m length of the ramp, it begins to slide horizontally along a rough, horizontal concrete surface with a coefficient of kinetic friction k = 0.394 until it slowsto a complete stop.How far does the block slide horizontally along the concrete before it stops? [Note : this question may contain more information than is necessary to solve the problem. Assume that no energy is lost to deformation or sound at the transition between the ramp and the concrete.]
