The position r of a particle moving in an xy plane is given by r = (2.00t

Question:

The position r of a particle moving in an xy plane is given by r = (2.00t³ – 5.00r)i + (6.00 – 7.00t⁴)j, with r in meters and t in seconds. In unit-vector notation, calculate

(a) r,

(b) v, and

(d) What is the angle between the positive direction of the x axis and a line tangent to the particle's path at t = 2.00 s?
