Q: A steel ball of mass 0.1 kg falls freely from a height of 10m and bounces to a height of 5.4 m from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is (specific heat of steel = 460 K/kg/°C, g = 10 m/s²)
(a) 0.01°C
(b) 0.1°C
(c) 1°C
(d) 1.1°C
Ans: (b)
