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 I am having trouble finding the normal force to this problem but I am also unsure as to how to calculate the force when no mass is given...im sure it cancels somehow but just don't see it. any help would be appreciated.
