# A body is projected up a smooth inclined plane with a velocity 𝑣0 from the point 𝐴 as shown in figure. The angle of inclination is 45° and top 𝐵 of the plane is connected to a well of diameter 40 m. If the body just manages to cross the well, what is the value of 𝑣0? Length of the inclined plane is 20√2m, and g = 10ms −2
