The figure shows the top view of an experimental rocket sled which is traveling at a speed of 1000 ft/sec when its forward scoop enters a water channel to act as a brake. The water is diverted at right angles relative to the motion of the sled. If the frontal flow area of the scoop is 15 in.², calculate the initial braking force. The specific weight of water is 62.4 lb/ft³.
