Answer:
The energy loss due to friction in one revolution is 4.92 J.
Explanation:
Given that,
Mass of particle = 0.358 kg
Radius = 1.66 m
Initial speed =8.19 m/s
Final speed = 6.29 m/s
We need to calculate the kinetic energy
Using formula of kinetic energy

Put the value into the formula


Hence, The energy loss due to friction in one revolution is 4.92 J.
