Question

5. For parts i, ii, and ii, find the vector's (a) magnitude and (b) angle relative to the positive x-axis: i) (150 N, 320 N) i) (0.251 lb, -1.34 Ib) i) (-4.5 kN, -1.2 kN) Use the following figure to answer problems 6 through 11: 5 35° 20° 6. Draw vector R P+Q (note: drawing does not need to be to scale, but think carefully about the sense of the components of R). 7. Using the law of cosines and law of sines, find the magnitude and direction of R P+Q 8. Calculate the x-and y-components of P and Q, and use them to calculate the x- and y-components of R. 9. Calculate Q P. 10. Using the following steps, calculate the parallel and perpendicular components of P along o. (a) Calculate ug, the unit vector in the direction of Q. (b) Calculate the parallel component of P in the direction of Q (c) Calculate the perpendicular component of P in the direction of Q 11. Calculate P × Q
