    Uniform Circular Motion-Velocity

    Homework Statement Here's the exact problem: Young David who slew Goliath experimented with slings before tackling the giant. He found that he could revolve a sling of length 0.650 m at the rate of 5.00 rev/s. If he increased the length to 0.950 m, he could revolve the sling only 3.00 times...
