Answer to Question #209831 in Physics for Maria Fe

Question

The breaking strength of a string is 500N.

Find the maximum speed that it can attain if a 1.5kg ball is attached at one end while the

other is held stationary and is whirled in a

circle. The string is 0.65m long.

Answer 1

$T=mv^2/r\to v=\sqrt{Tr/m}=\sqrt{500\cdot 0.65/1.5}=14.72\ (m/s)$ . Answer
