A body is projected up a smooth inclined plane with a velocity u from the point A as shown in the figure. The angle of inclination is 45 degrees and the top is connected to a well of diameter 40 m. If the body just manages to cross the well, what is the value of u? Length of inclined plane is 20 2 20\sqrt { 2 } .

40 20 3 20\sqrt {3 } 40 3 40\sqrt { 3 } 20 2 20\sqrt { 2 }
