Particle is at (9, 4) on coordinate plane.
Initial velocity: 5.5 x - 7 y
Acceleration: 1 x + 8.5 y
1: What is the x-component of velocity after that 1.5s?
3: Magnitude from origin of graph?
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?
