You are working for a shipping company. Your job is to stand at the bottom of a 8.0-m-long ramp that is inclined at 37 degress 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 mu_k=0.30.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? I think im having trouble finding the normal force to this problem but im also unsure as to how to calculate the force when no mass is given...im sure it cancels somehow but just dont see it. any help would be appreciated.
