Answer to Question #339693 in Physics for Klaus

Question

A string is 6.17 m long with a mass of 3.37 g. The string is held taut with a tension of 448 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?

Round your answer to 5 decimal places.

Do not forget the unit

Answer 1

$$v=\sqrt{F/(m/l)}$$

$$v=\sqrt{448/(0.00337/6.17)}=906\:\rm m/s$$

$$\Delta t=\frac{d}{v}=\frac{3.00}{906}=0.0033\:\rm s$$
