What is the speed of the stone for each rate of rotation

Reference no: EM13525629

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 9.00 rev/s. If he increased the length to 0.950 m, he could revolve the sling only 7.00 times per second.
