Question: At a mail sorting facility, packages slide down a ramp but are stopped part way down the ramp so that they can be scanned.

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. The ramp makes an angle of 0 = 35.5" with the horizontal. The package has a mass of 9.75 kg. The coefficient of static friction between the ramp and the package is 0.395. Calculate the minimum force Fin that this arm must apply to hold a package on the ramp. 8.134 Fmin N min Incorrect
