A float is used to test the flow pattern of a stream. It follows a path described by x= Begin by finding expressions for the x- and y-components of the acceleration. ax = (Type ex and ay = feet per minute feet squared per minute feet per minute squared =0.4t, y= = 0.3t (x and y in ft, t in min). Find the acceleration of the float after 2.0 min. The x- and y-coordinates of a moving particle are given by the parametric equations below. Find the magnitude and direction of the acceleration for the specific value of t. x=4t, y=4-t, t=3 Find the magnitude of the acceleration of the particle for the specific value of t. The magnitude is approximately (Type an integer or decimal rounded to two decimal places as needed.)
