A horizontal 5-cm-diameter water jet with a velocit of 18 m/s impinges normally upon a vertical plate of J 1000 kg. The plate is held in a nearly frictionless track and is initially stationary. When the jet strikes the plate, the piaie begins to move in the direction of the jet. The water always splatters in the plane of the retreating plate. Determine (a) L acceleration of the plate when the jet first strikes it (time = 0) (b) the time it will take for the plate to reach a velocity of 9 m/s, and (c) the plate velocity 20 s after the jet first strikes the plate. Assume the velocity of the jet relative to the plate remains constant.
