A gladiator is using a ball and chain as a weapon (assume its moment of inertia is similar to a thin hoop). The mass of the chain is negligible and it is 1.25 m in length. The mass of the ball, located at the end of the chain, is 3.0 kg. If the gladiator starts to accelerate the ball and chain from rest to 5 rpm determine
(a)The moment of inertia of the ball and chain.
(b)The rotational kinetic energy of the ball and chain at 5 rpm.
(c)If it took 3 s for the gladiator to get the ball and chain up to speed, what was the average torque applied?
(d)Assuming the gladiator continues to apply the torque in a constant manner, how much power must the gladiator exert?
