In a perfectly inelastic collision, two spheres made of the same material with masses 15 kg and 25 kg, moving in opposite directions with speeds of 
and 
, respectively, strike each other and stick together. The rise in temperature (in 
), if all the heat produced during the collision is retained by these spheres, is : (specific heat of sphere material 
and 
)
