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
(c) a for t = 2.00s.
(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?
