Traditional slingshots of old were made from camel hair and are, on average, about 80 cm in length. Rocks can be thrown from a slingshot up to 75 m/s at release.
a.) What angular acceleration is necessary if someone is to reach this speed, starting from rest, in 10 total spins of the slingshot?
b.) How long would it take to reach this speed?
