Beginning from rest, a block of mass m slides down a frictionless curve. after sliding downward by h = 0.60 m, the block encounters horizontal concrete and slides to a stop. the coefficient of kinetic friction between the block and the concrete is µk = 0.30. what is the stopping distance l?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
