a simple pendulum of length 0.2m has bob of mass 5gm, it is pulled aside through an angle 60 degrees from the vertical. a spherical body of mass 2.5gm is placed at the lowest position of the bob. when the bob is released it strikes the spherical body and comes to rest.what is the velocity of the spherical body?(g=9.8 m/s)
