At a mail sorting facility, packages slide down a ramp but are stopped part way down the ramp so that they can be scanned. while the packages are scanned, they are held in place by a horizontal force from a spring-loaded arm. calculate the minimum force that must be applied by this arm to hold a package on the ramp. the ramp is at an angle of 33.5° with the horizontal. the package has a mass of 9.25 kg. the coefficient of static friction between the ramp and the package is 0.455.
