A particle’s trajectory is described by x = (1/2t ^{3} - 2t ^{2}) m and y = (1/2t ^{2} - 2t) m, where t is in seconds.

(a) What are the particle’s position and speed at t = 0 s and t = 4 s?

(b) What is the particle’s direction of motion, measured as an angle from the x-axis, at t = 0 s and t = 4 s?
