[QUOTE="Austin Gibson, post: 6069313, member: 650849"] [B][h2]Homework Statement [/h2][/B] "Consider the 65.0-kg ice skater being pushed by two others as shown in the figure below." Figure: [URL]https://gyazo.com/9d7525071f54b00ea7e720abdeb50594[/URL] [ATTACH=full]231937[/ATTACH] Find the total force exerted on her by the others, given that F1 = 21N and F2 = 36N. Express your answer in vectorm form.[h2]Homework Equations[/h2] I doubt "F=ma" is relevant for this question considering we're merely calculating the force directed towards the skater instead of her movement thereafter.[h2]The Attempt at a Solution[/h2] I calculated the components of F1 and F2 with the following numbers: I judged the angle of F1 to be (360 - 24 = 336). F1: 21cos336 (x-component) + 21sin336 (y-component). I judged the angle of F2 to be (90 - 24 = 66). F2: 36cos66 (x-component) + 36sin66 (y-component). I calculated the sum of these as 33.84i + 24.35j. Judging by the picture, are my translations of the angles correct? Any guidance is appreciated. [B] [/B] [/QUOTE]
