Answer:
2.943 J
Explanation:
Data:
acceleration due to gravity, g = 9.81 m/s²
mass of sand = 0.5 kg
distance = 0.6
Thermal energy = the energy possessed by the falling sand
The force of sand = ma
=
However, the energy is given as the force multiplied by the distance, so
E =fd
Therefore, the thermal energy is 2.943 joules
