A jet of water issuing from a nozzle strikes a flat plate normally (plane of plate makes an angle 90° with the axis of the jet). The plate moves away from the nozzle with a velocity of 10 m/s while the jet issuing from the nozzle has a velocity of 15 m/s. The absolute velocity components of the jet (in m/s) after it strikes the plate, parallel (x component) and normal component (y component) to the undisturbed jet are. (Neglect friction on the surface). |
