A particle's trajectory is described by x=((1/2)t^3 - 2t^2) and y=((1/2)t^2-2t) , where t is in s.
What is the particle's speed at t= 4.5 s?
What is the particle's direction of motion, measured as an angle from the x-axis, at t=4.5 s?
I keep geting the wrong answers >:0 , how do I go about solving this?
