QUIZ ONE 1.) What are scalar and vector? Explain using an example for each. Scalar - a quantity that can be described with a single number, including any digits, giving its size or magnitude. Vector - a quantity that deals inherently with both magnitude and direction 2.) What is the negative of a vector? For example if vector A has a value of 10 units and points towards east then what is vector –A? The negative of a vector is a vector moving in the opposite direction of the original vector. If a vector has a value of 10 units and points east, vector –A has a value of 10 units and points west. 3.) Vector A points due west, while vector B points due south. A) Does the direction of A+B point north south of due west? B) Does the direction of A-B point north or south of due west? Give your reasoning in each case. a) A+B points south of due west a. Vector A points west and vector B points south b) A-B points north of due west a. Because –B is the opposite direction of B which points south, therefore –B points north 4.) Two Vectors A and B are added together to form vector C. The vectors A and B are perpendicular to each other. What is the relationship between the magnitudes of vectors A, B, and C? Explain using a drawing. 5.) The Figure to the left shows three displacement vectors A, B, and C. These vectors are arranged in tail-to-head fashion, because they add together to give a resultant displacement R, which lies along the x-axis. What is the magnitude of vector C? (#,p) 6.) The corners of a square lie on a circle of diameter D = 0.35 m. Each side of the square has a length of L. Find L. (#,p)

7.) Vector A Has a magnitude of 63 units and points due west, while vector B has the same magnitude and points due south. Find the magnitude and direction of (a) A+B and (b) A – B. specify the directions relative to due west. (#,p) 8.) A baby elephant is stuck in a mud hole. To help pull it out, game keepers use a rope to apply force F A as part a of the drawing shows. By itself, however force F A is insufficient. Therefore two additional forces F
