The x- and ycoordinates of a moving particle are given by the parametric equations below. Find the magnitude and direction of the velocity for the specic value oft. Sketch the curve and show the velocity and its components. x=3t,y=4t,t=3 l' ..... " Find the magnitude of the velocity of the particle for the specic value of t. The magnitude is approximately E. (Type an integer or decimal rounded to two decimal places as needed.)
