Answer Key / Explanation : (c) -
(c)
P.E. of bob at point 
This amount of energy will be converted into kinetic energy
.png)
K.E. of bob at point 
And as the collision between bob and block (of same mass) is elastic so after collision bob will come to rest and total Kinetic energy will be transferred to block. So kinetic energy of block
