This Olympic athlete is competing in the disk throwing event. If on the second throw, he increased his rope by twice as long, how would it affect the MAGNITUDE of the tangential velocity?

Hint:  $V=\left(\frac{2\pi r}{T}\right)$ 

• twice as great

• 4 times greater

• twice lessoned

• it will not be affected.

Answer explanation

Looking at the formula $V=\left(\frac{2\pi r}{T}\right)$ where the radius is in the numerator. Therefore we must multiply by two on both sides of the equation on the numerator sides.
