The hour hand and minute hand for the famous parliament clock tower big ben in london are 2.7 and 4.5 m long and have masses of 60kg and 100 kg. determine the total rotational kineti cenergy of these hands

0.00102 J

Explanation:

h denotes hour hand

m denotes minute hand

Mass of hour hand = 60 kg

Mass of minute hand = 100 kg

Length of hour hand = 2.7 m

Length of minute hand = 4.5 m

Angular velocity is given by

Moment of inertia is given by

Total kinetic energy is given by

The total kinetic energy of the system is 0.00102 J

less than one you can't create energy

do you have a formula possibly
