1. The problem statement, all variables and given/known data Particle is at (9, 4) on coordinate plane. Initial velocity: 5.5 x - 7 y Acceleration: 1 x + 8.5 y Time: 1.5s 1: What is the x-component of velocity after that 1.5s? 2: Y-component? 3: Magnitude from origin of graph? 2. Relevant equations sqrt(x^2 + y^2) for magnitude, tan^-1(y/x) for angles. 3. The attempt at a solution Dunno if I'm on the right track, but based on the above: Initial velocity: 8.9022, -51.8428° Acceleration: 8.5586, 83.2902° The inclusion of acceleration and velocity as opposed to simple vector addition has got me a bit screwed up. What should I do with this?
