Question:

The coordinates of a particle which moves with curvilinear motion are given by x = 10.25t + 1.75t2 − 0.45t3 and y = 6.32 + 14.65t − 2.48t2, where x and y are in millimeters and the time t is in seconds. Determine the values of u, v, a, a, er, eθ, vr, vr, vθ, vθ, ar, ar, aθ, aθ, r, r˙, r¨, θ, θ˙, and θ¨ when t = 3.25 s. Express all vectors in terms of the unit vectors i and j. Take the r-coordinate to proceed from the origin, and take θ to be measured positive counterclockwise from the positive x-axis.
