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.

Q3. As shown on the right in image below, the force Facting on the box varies with displacement s, and the coefficient in the image, C = 14. Determine the work done by force Fto the box when the box has displaced s = 1.9 m. Please pay attention: the numbers may change since they are randomized. Negative sign must be included if the work done is negative. Your answer must include 2 places after the decimal point, and proper SI unit. F (N) F 5 3 S 4 C s (m) 1 2
Blocks mị and m2 are connected by a rope as shown in the figure. There is friction between mi and the wall, where the coefficient of static friction is ls. There is no friction between m2 and the ramp. An unknown force P is applied to mį so that mị is about to slip down the wall and m2 is about to move down the ramp. If the magnitude of the normal force on m2 is n2, find m2, the magnitude of P, the magnitude of the friction force on m1, and the magnitude of the tension force in the rope. The knowns are ls, n2, m1, g, and 0. P = ? Hs rope wall no friction m2 = ? ramp
