Physics 20 Lesson 16 Friction
structuredindependentlearning.com8. A boy pulls a 50 kg crate across a level floor with a force of 200 N. If the force acts at an angle of 30o up from the horizontal, and the coefficient of kinetic friction is 0.30, determine (a) the normal force exerted on the crate by the floor, (3.9 x 102 N) (b) the frictional force exerted on the crate by the floor, (1.2 x 102 N)
