Four vectors A, B, C, and D are shown (not to scale). Vector A has magnitude 20.0 and acts at an angle of 12.9 degrees with respect to the positive x axis. Vector B has magnitude 15.0 and acts at an angle of 55.7 degrees with respect to the positive x axis. Vector C has...
alright, i made a right triangle with the x and y being the two sides and the given 90 degrees. it didn't get me anywhere earlier since I didn't have any values. I couldn't figure out how to calculate the values of the horizontal and vertical degrees of the strings, so I went with that triangle...
Homework Statement
"a spider is resting after starting to spin its web. The gravitational force on the spider is 0.172 N on the junction of the three strands of silk. The junction is supported by different tension forces in the two strands above it so that the resultant force on the junction...
