Algebra 2 Linear Equations: Learn and Solve

The velocity in a certain two-dimensional flow field is given by the equation
$V = 2 x t \hat{i} - 2 y t \hat{j}$
where the velocity is in ft/s when x, y, and t are in feet and seconds, respectively. Determine expressions for the local and convective components of acceleration in the x and y directions. What is the magnitude and direction of the velocity and the acceleration at the point x = y = 2 ft at the time t = 0?
