Unformatted text preview: pavlyukovskyy (mp24573) – Homework 4 – Weathers – (17104) 1 This printout should have 11 questions. Multiplechoice 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 θ 1 = 130 ◦ , θ 2 = 140 ◦ , θ 3 = 33 ◦ , and θ 4 = 54 ◦ , measured from the positive x axis with the counterclockwise 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 ◦ ....
