Three forces acting on an object are given by F1 = (−1.85i+ 6.35j) N, F2 = (4.90i − 1.15j) N, and F3 = (−44.5i) N. The object experiences an acceleration of magnitude 3.55 m/s2. They want the velocity components of the object after 4 seconds. First, I calculated the direction of the acceleration to be 169.74 degrees, which it says is correct. So, I went and calculated its speed after 14 seconds, and I got 49.7 m/s and it says its right. Then, I went and and calculated vx=49.7*cos(169.74) and got it right. However, when I go to calculate vy=49.7*sin(169.74), it says its wrong but "I calculated the y component correctly using my incorrect values from above". Yet I got all of the above information right...can anyone help if I'm doing something wrong when calculating vy? Thanks!
