Lesson 3 Homework 1. A bear walks northeast for 12 m and then east for 12 m. Show each displacement graphically and find the resultant displacement vector. 2. Find the rectangular components of a vector v that has a magnitude of 12 ms -1 and is oriented at an angle 37 o with the positive x-axis. 3. A vector A has an x-component -4.5 m and a y-component 2.2 m. What is the magnitude and direction of vector A? 4. Find the resultant of the following vectors: 30 o 30 o 45 o 20 N 15N 25 N 5. Find the x and y components of the velocity vector 16 m/s at an angle 108 o with the positive x axis. 6. Following are three vectors A , B and C : A = 16 i – 2 j B = -5 i + 8 j C = 2 i + 5 j Find the magnitude and direction of (i) A + B + C (ii) A B + C (iii) 2 A B – 3 C 7. Two force vectors F 1 = 3.0 N i 3.0 N j and F 2 = -6.0 N i + 4.5 N j are applied to a particle. What force F 3 applied on the particle will make the net force on the particle zero? 8.
