You are working for a shipping company. Your job is to stand at the bottom of an 8.0-m-long ramp that is inclined at an angle of 17 degrees above the horizontal. You grab packages off a conveyor belt and propel them up the ramp. The coefficient of kinetic friction between the packages and the ramp is uk =0.30. (a) 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?
