A force of 200 N will keep this crate from slipping down the 37 degree incline. A 400 N force will keep the crate from moving up the incline. Determine the static coefficient of friction and the mass of the crate. Determine the mass using a quadratic formula. Then proceed to determine the static coefficient of friction. Determine the magnitude of the friction force in both cases and with a 1 m square crate, determine thelocation of the resultant normal force.
