An alien UFO was observed to be moving on an x-y plane in Collinder 50 in the outer space. The coordinates of this alien UFO is given as a function of time: x(t) = W(at - sin[at]) y(t) = W(1 -cos[at]) a. Draw the displacement of the UFO from t=0 to t= 4m (you may use Excel on this, and plot with time interval, It/2). b. What are the x and y components of velocity and acceleration vectors at any given time (expressed in t)? What are these components at t=0? ONLY BASED YOUR ANSWER ON THE GIVEN NUMBERS BELOW. (GROUP 8)
