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 s.a) what is the particles speed at t=0?b) t=3?c) what is the particle's direction of motion, measured as an angle from the x - axis, at t=0's?d) What is the particle's direction of motion, measured as an angle from the x - axis, at t=3.0 s?
