1. The problem statement, all variables and given/known data A force of 2N east and a force of 3N 25degrees N of E act on an object. What is the net force on the object? The answer according to the text is 4.9N 75Degrees E of N 2. Relevant equations 3. The attempt at a solution First express direction in terms of x-axis: Resolve 2N East into x and y components Rx = R cos Theta Ry = R sin Theta =2Ncos180 =2Nsin180 = -1.9N =0 Resolve 3N 25degrees N of E into x and y components Rx = R cos Theta Ry = R sin Theta =3cos335degrees =3sin335degrees =1.6N = -2.6N Add x components Rx=R1x+R2x = -1.9N + 1.6N = -0.3N west direction because of minus sign Add y components Ry=R1y+R2y =0N + -2.6N = -2.6N south direction because of minus sign Add Rx and Ry to obtain R R= sqrt Rx^2 + Ry^2 = -0.3^2 + -2.6^2 = sqrt of 6.85 = 2.62N arc tan -0.3/-2.6= theta I don't understand how the answer is what they got? Please help?
