You are working for a shipping company. Your job is to stand at the bottom of a 7.0 m -long ramp that is inclined at 45 " above the horizontal. You grab packages off a conveyor belt and propel them up the ramp. The coefficient of What speed do you need to give a package at the bottom of the ramp so that it has zero speed at the top of the ramp? kinetic friction between the packages and the ramp is / = 0.30. Express your answer in meters per second. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of A steeper hill.
