The water from a fire hose follows a path described by y=2.0+0.8x-0.20x^2 ?(units are in? meters). If vx is constant at 5.0 ?m/s, find the resultant velocity at the point (4.0,2.0).
Find the magnitude of the velocity of the water at the point (4.0,2.0).
Find the direction of the velocity of the water at the point (4.0,2.0). Enter an angle?
