Two identical blocks after impact

are attached. If $20\%$ of the heat

generated in the impact is absorbed by the

Blocks. What temperature variation

will you experience the blocks? Consider that

Before impact the blocks have the same

temperature.

$($Cewoquc$=0\mathrm{.}06$ cal$/$g$$C$)$ the block going to the right has a velocity of $3$m$/$s and the one going to the right has $2$ m$/$a
