The person an the right pulls with a force F1 of magnitude 73.4 N and direction of I91 : 70.0\". The person on the left pulls with a _. forceF2 of magnitude 71.4 N and direction of 62 : 75.0\". G) (a) Find the single force that is equivalent to the two forces shown. The forces are measured in units of newtons (symbolized N). [b] Find the force that a third person would have to exert on the mule to make the resultant force equal to zero. :NHEM Need Help? 15. [-12 Points] SERPSE10 3.4.P.03'l. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You are standing on the ground at the origin of a coordinate system. An airplane flies over you with constant yeIOCity parallel to the x was and at a constant height of 6.60 x 103 m. At t : O, the airplane is directly above you so that the vector leading from you to it is so : 6.60 x 103i rn. At t : 30.0 s the position ye(tor leading from you to the airplane is 530 : (7.00 x103i+ 6.60 x103j) m as suggested in the figure below. Determine the magnitude and orientation of the airplane's position vector at t : 60.0 5. direction \\:I 5 above the horizontal Need Help? _
