Question

the helicoter view show two people pulling a stubborn mule.the first person pulls with force of 120 newtons at an angle of 60degrees above the position x-axis. the second person pull with aforce of 80.0 newtons at an angle of 75 degrees above the negativex-axis a. find the magnitude of the single force that is equivalentto the forces shown b. at one (or what) angle is that sigle force(measure the angle from the positive x-axis) c. with what force would a single person have to pull the muleto make the total force equal to zero d. what direction should they pull to make the net force eqalto zero (you should express this angle as measured from thepositive x-axis) please give me the steps and how you figured it out i amworking out of the book essential of college physics by(Serway/Vuille) ISBN 0-495-10619-4 the helicoter view show two people pulling a stubborn mule.the first person pulls with force of 120 newtons at an angle of 60degrees above the position x-axis. the second person pull with aforce of 80.0 newtons at an angle of 75 degrees above the negativex-axis a. find the magnitude of the single force that is equivalentto the forces shown b. at one (or what) angle is that sigle force(measure the angle from the positive x-axis) c. with what force would a single person have to pull the muleto make the total force equal to zero d. what direction should they pull to make the net force eqalto zero (you should express this angle as measured from thepositive x-axis) please give me the steps and how you figured it out i amworking out of the book essential of college physics by(Serway/Vuille) ISBN 0-495-10619-4

Explanation / Answer

Fx = 120cos(60) - 80.0cos(75) = 39.29 N Fy = 120sin(60) + 80.0sin(75) = 181.20 N a) F = (Fx2 +Fy2) = 185.4 N b) = tan-1(Fy/Fx) =77.8o c) 185.4 N d) 180 + 77.8 = 257.8o
