Explanation / Answer

According to the given problem,

4.) The angle of velocity vector,

= Tan-1[-16/-57]

= 180 + Tan-1[16/57] [From x component and y component of velocity it can said that vector is in Q3] and Tan is +ve in this Quadrant.

= 195.68o

5.) Given,

F = 43lb and Fx = - 22lb [As it is in Q3]

Using magnitude formula,

F2 = Fx2 + Fy2

F2y = 1365

Fy = - 36.9459 [as its in Q3]

Fy = - 37 lb.

6.) As we did in question 4.

= Tan-1[-37/-22]

= 180 + Tan-1[37/22] [From x component and y component of Force it can said that vector is in Q3] and Tan is +ve in this Quadrant.

= 239.23o
