- Only handwritten answer is needed pleasearrow_forwardAnswer for the 1st part of the problem. magnitude of force A = 74 N direction of force A = 25o north of west second force = P direction of force P = α south of west arrow_forward The resultant of two forces is horizontal , it means that the y component of resultant = 0 Ry = ASin(25o) - PSin(α) 0 = (74×0.42) - PSin(α) PSin(α) = 31.08 NFor, the smallest force P , the value of Sinα must be maximum which is 1 when the value of αis 90 degree Thus, P×Sin(90o) = 31.08 N P = 31.08 N The magnitude of smallest force P = 31.08 N the direction of force P = 90 degree south of west = along - y axis= arrow pointing vertically downwarrow_forwardAlso, determine angle that T makes with the positive y-axis. Your answer should be in the range 180 ≤ ang > -180. Also, determine angle that T makes with the positive z-axis. Your answer should be in the range 180 ≤ ang > -180.arrow_forward
