CO PHYSICS 150 LAB QUIZ REVIEW! Composition of Concurrent Forces Name Luke Swearingen The diagram below shows a top view of a force table. Two weights are hung on the force table at the following positions: 100 grams at 0 150 grams at 300 00. cos ( 0) m, 100. sin (0) m - 100, 0 150 . cos (300)m, 150 . sin ( 300)m 75, - 129. 90381 (a) Find the resultant pulling force by adding these two vectors. 90 175 , - 129 , 90381 120 0 60 Mass 217,94494 grams 150 Angle - 36.598 300 180 100 g VI( 175) 2 + (- 129, 90381)27: 217. 94494 grams 210 330 240 300 ARCTAN(-T29 90381) : - 36.590 270 150 g 175 (b) At what angle should a third weight be hung so that the net force on the black ring is zero? 50.7+ 180 (c) How many grams should this third weight have
