A small block having a mass of 0.1 kg is given a horizontal velocity of v1 = 0.4 m/s when r1, = 500 mm. It slides along the smooth conical surface. Determine the distance h it must descend for it to reach a speed of v2 = 2 m/s. Also, what is the angle of descent θ, that is the angle measured from the horizontal to the tangent of the path?
