A steel ball of mass m1 = 1 kg moving with velocity 50 ms'1 collides with another steel ball of mass m2 = 200 g lying on the ground. During the collision, their internal energies change equally and T1 and T2 are the rise in temperatures of masses m1 and m2, respectively. If specific heat of steel is 0.105 and mechanical equivalent of heat is 4.18 Jcal'1, then
