A net is dipped in a river. Determine the flow rate of water across the net if the velocity vector field for the river is given by v = (x- y, z+y+7, 2²) and the net is decribed by the equation y = √1-x²-2², y ≥ 0, and oriented in the positive y-direction. (Use symbolic notation and fractions where needed.) [[¸y - ds =
