I'm given a statement such as the vector position of a particle varies in time according to the expression r = (8.60 i - 8.40t^2 j) m.
Somehow, i have to find expressions for the velocity and acceleration as functions of time. (Using t, i, and j as necessary.); and determine the particle's position and velocity at t = 3.00 s.
Unfortunately, I'm not even sure how to rearrange it (or what its wanting me to rearrange into a function a T)
