Homework Statement
Young David who slew Goliath experimented with slings before tackling the giant. He found that he could revolve a sling of length 0.750 m at the rate of 10.0 rev/s. If he increased the length to 1.050 m, he could revolve the sling only 8.00 times per second.
What is the speed of the stone for each rate of rotation?
a) ... m/s at 10.0 rev/s
b) ... m/s at 8.00 rev/s
The Attempt at a Solution
I can probably figure this out but I forgot my book and don't want to guess. Please could you tell me the equation that I use.
Thanks.
