(A) $1$. When the first sphere (mass $m = 0.1 \ kg$) is released from a horizontal position of length $l = 1 \ m$,its potential energy is converted into kinetic energy at the bottom point.$2$. The kinetic energy $K_1$ of the first sphere just before the collision is $K_1 = mgh = 0.1 \ kg 	imes 10 \ m/s^2 	imes 1 \ m = 1 \ J$.$3$. In a perfectly elastic collision between two bodies of equal mass where one is initially at rest,the bodies exchange their velocities.$4$. Therefore,the first sphere comes to rest,and the second sphere gains the entire kinetic energy of the first sphere.$5$. The kinetic energy gained by the second sphere is $1 \ J$.

$A$ sphere of mass $0.1 \ kg$ is attached to a string of length $1 \ m$. It is released from a horizontal position and collides with another sphere of equal mass $m$ at rest. Find the kinetic energy gained by the second sphere. The collision is perfectly elastic. (in $J$)
