3. A 283-N block is in contact with a plane inclined at 38° to the horizontal. A force P, parallel toand acting up to the plane, applied to the body. If the coefficient of static friction is 0.3, (a) Find the value of P to just cause motion to impend up the plane (b) Find P to just prevent motion down the plane (c) If P = 87 N, determine the magnitude and direction of the friction force(Final answers in N, 3 decimal places)

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
