Find the object's velocity and position at t = 3.00 s. Express both (c) the velocity vector and the position vector in component form and magnitude-angle form. [Note: Don't forget to treat the x and y motion independently!] At t = 3.00 s, find the change in the object's kinetic energy two ways: (d) i) using AK = m(v; – v?)/2, and ii) using W = F. d.
