Young David, who slew Goliath, experimented with slings before tackling the giant. He found that with a sling of length 0.54 m, he could revolve the sling at the rate of 7.06 rev/s. If he increased the length to 0.828 m, he could revolve the sling only 3.66 rev/s.

a) What is the larger of the two linear speeds? Answer in units of m/s.b) Using the sling length 0.828 m, what is the centripetal acceleration at 3.66 rev/s? Answer in units of m/s

v = 7.06 rev/sec (2πr distance/rev)

v₁ = 23.95 m/s

v₂ = 3.66 rev/sec (2πr .828m/rev) = 19.0 m/s
