Unformatted text preview: pavlyukovskyy (mp24573) Homework 4 Weathers (17104) 1 This print-out should have 11 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points Consider four vectors vector F 1 , vector F 2 , vector F 3 , and vector F 4 , where their magnitudes are F 1 = 30 N, F 2 = 21 N, F 3 = 23 N, and F 4 = 64 N. Let 1 = 130 , 2 =- 140 , 3 = 33 , and 4 =- 54 , measured from the positive x axis with the counter-clockwise angular direction as positive. What is the magnitude of the resultant vec- tor vector F , where vector F = vector F 1 + vector F 2 + vector F 3 + vector F 4 ? Answer in units of N. 002 (part 2 of 2) 10.0 points What is the direction of this resultant vector vector F ? Note: Give the angle in degrees, use coun- terclockwise as the positive angular direction, between the limits of- 180 and +180 from the positive x axis. Answer in units of ....
