## Homework Statement

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?

## Homework Equations

sqrt(x^2 + y^2) for magnitude, tan^-1(y/x) for angles.

## 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?
