Question

A snowboarder starts from rest on an inclined planar snow surface and gives herself a tiny push to start sliding down the hill. The coefficient of kinetic friction between her snowboard and the snow is 0.08. She notices that she travels 26.53 m horizontally and 34.51 m vertically (downward) before whizzing by a marker flag. How fast is she traveling as she passes the flag?
