Q44 · Physics

Bob B of mass m at rest is hanging vertically from the ceiling via a massless string of length 10 m, as shown in the figure. Point mass A of mass m travelling horizontally with speed 10 ms−1^{-1} hits bob B elastically. The bob B rises h meter after the collision. Taking the acceleration due to gravity g = 10 ms−2^{-2} and neglecting the size of the bob, the value of h is :

The figure, described in words

Bob B hanging from the ceiling on a vertical string; point mass A moving horizontally towards B at 10 m s−1^{-1}.
