Unformatted text preview: sanchez (es25396) Homework #4 Vectors, Horizontal Projectiles guevara (130101) 1 This print-out should have 12 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A person walks 30 m East and then walks 35 m at an angle 47 North of East. What is the magnitude of the total dis- placement? Answer in units of m. 002 (part 1 of 2) 10.0 points Given two vectors vector F 1 , and vector F 2 . Where the magnitude of these vectors are F 1 = 78 N , and F 2 = 56 N . And where 1 = 27 , and 2 = 78 . The angles are measure from the positive x axis with the counter-clockwise angular direc- tion as positive. What is the magnitude of the resultant vec- tor bardbl vector F bardbl , where vector F = vector F 1 + vector F 2 ? Answer in units of N. 003 (part 2 of 2) 10.0 points Note: Give the angle in degrees, use coun- terclockwise as the positive angular direction, between the limits of 180...
