<span>The heat energy is being transferred between the two substances by thermal conduction. Because the hot coffee is at a different temperature to the mug, heat energy flows between them so that they reach thermal equilibrium, or the same temperature. This kind of heat transfer always happens from hotter temperatures to cooler temperatures.</span>
Answer:
Kinetic energy is 242.7 Joule
Explanation:
m = 47.4 kg
v = 3.2m/s²
Now,
K.E. = 1/2 × m × v²
or, K.E. = 1/2 × 47.4 × 3.2²
or, K.E. = 242.7 Joule
