1. The problem statement, all variables and given/known data What is the y-component of a vector in the x-y plane whose magnitude is 86.4 and whose x-component is 62.3? 59.9 2. Relevant equations a^2 + b^2 = c^2 Sin-1= Vy/|v| 3. The attempt at a solution a^2 + b^2 = c^2 And 59.9 was right for that, but i used Sin-1= Vy/|v| for the angle and got: Sin-1= 59.86/ 86.4 = 43.85° but that wasn't right. Can anyone offer me some insight?
