Unformatted text preview: rotational kinetic energy of the system when it rotates 0.5 times per second about the center? (Ignore the size of the balls.) 4 m 2 m A top (r=0.5m) spins around 10 times every second. If most of the mass is concentrated in the disk, what is the moment of inertia of the top? A top (r=0.5m) spins around 10 times every second. If most of the mass is concentrated in the disk, what is the rotational kinetic energy of the top? A top (r=0.5m) spins around 10 times every second. If most of the mass is concentrated in the disk, what is the rotational kinetic energy of the top? A 4kg ball rotates around the green post below 3 times per minute. The ball has a radius of 2m and the center of the ball is 5m away from the post. What is the rotational kinetic energy of the ball....
