saenz (bds2323) Chapter 04 Forces pad aspiret (15122) This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page ?nd wholly choices before resul tangentting. 001 (part 1 of 2) 10.0 points A man is pulling on a rope with a draw in of 56 N directed at an angle of 62? to the horizontal. What is the x-component of this legions? tame decide: 26.2904 N. news report: Let : F = 56 N and ? = 62? . news report: Fy = F trespass ? = (56 N) sin 62? = 49.4451 N . 1 003 (part 1 of 4) 10.0 points A crate is pulled to the right with a force of 89.9 N, to the left with a force of 114.4 N, upward with a force of 627.4 N, and downward with a force of 242.9 N. a) What is the net outdoor(a) force in the x head? Correct answer: ?24.5 N. Explanation: 627.4 N ?114.4 N 56 N 89.9 N ?242.9 N Note: lick is not cadaverous to scale. canonic invention: Fx,net = Fx,1 + Fx,2 tending(p): 62 ? scale click: 10 N Fx,1 = 89 .9 N Fx,2 = ?114.4 N solving: Fx,net = 89.9 N ? 114.4 N = ?24.5 N , which is directed to the left. Fx = F romaine lettuce ? = (56 N) cos 62? = 26.2904 N . 002 (part 2 of 2) 10.0 points What is the y-component of this force? Correct answer: 49.4451 N. 004 (part 2 of 4) 10.0 points b) What is the net external force in the y direction?

saenz (bds2323) Chapter 04 Forces padgett (15122) Correct answer: 384.5 N. Explanation: Basic Concept: Fy,net = Fy,1 + Fy,2 Given: Fy,1 = 627.4 N Fy,2 = ?242.9 N Solution: Fy,net = 627.4 N ? 242.9 N = 384.5 N , which is directed up. 005 (part 3 of 4) 10.0 points c) What is the magnitude of the net external force on the crate? Correct answer: 385. 28 N. Explanation: F ? ?24.5 N Note: Figure ! is not drawn to scale. Basic Concept: Fnet = Solution: Fnet = (?24.5 N)2 + (384.5 N)2 (Fx,net )2 + (Fy,net )2 1.2 N ?9.11 N ? Fnet Solution: ? = tan?1 Fy,net Fx,net 384.5 N = tan?1 ?24.5 N = ?86.3541? Explanation: Basic Concept: tan ? = Fy,net Fx,net 2 to a higher place the negative x axis. Thus the direction is ? = 180.0? ?...If you want to get a plenteous essay, order it on our website: OrderEssay.net
