Question

I need #3,4 and 5. Ans is already given

Practice Problems in Working with Vectors Add each of the following sets of vectors, using the component method as outlined in this section. All angles given are measured from the positive x axis. 1. Ā: 25 m, 40° B: 42 m, 80° 2. Ā: 25 m/s, 55° 8:30 m/s, 1250 3. Ā: 12 m, 160° B: 18 m, 275° C: 22 m, 195° 4. Subtract C from B B:25 m/s, 120° C: 15 m/s, 35° 5. While on a hike, Alice walks 500 m at 30° N of E, then 750 m N, then 800 m at 10° S of W. What is Alice's resultant displacement from her starting position?

Answer 1

According to CHEGG's rule, only the first question is answered. Post rest questions separately.

Ā = 12m, 160° 5 = 18m, 275° ē - 22 m, 195 160 N 1959 of we will derive x and y component each vector Ão 3 and c. Ax = A Coso = 12 Cos 160° = - 11.28 Ay = A Sindi = 12 sin 160 = 4.10 unt ut B x = B Crs O2 = 18 Cos 275 = 1.57. unt By = B Sen Or = 18 sin 275- = - 17.93 unit Cx = c Com O₂ = 22 Cos 195 = - 21,25 mit Cy = ein Oz = 22 sen 19 . =- 5.69 uut Resultant: Ra=(-11-28 +1:57 - 21:25) unt = – 30.96 unit Ry= (4.10- 17.93 – 5.69 ) unt - 19.52 unit. Magnitude Resultant of vector = R = √ Rx² + Ry?

R= √ (30.96)²+(19.522 unit R = 36.60 unit. I Direction, & = tan Al tant 19.52 30.96 3223°. 180°+ 32. 23° = 212 23" from x-axis and 32.23° below Angle (t) ve negative x-axis . 30.96 19.52 R. Y Answer :- R: 36.60 unit. direction = 212.230
The answer provided is not correct as per several checking.
