Unformatted text preview: sanchez (es25396) – Homework #4 Vectors, Horizontal Projectiles – guevara – (130101) 1 This printout should have 12 questions. Multiplechoice 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 θ 1 = 27 ◦ , and θ 2 = 78 ◦ . The angles are measure from the positive x axis with the counterclockwise 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 ◦...
