The formula to calculate the material velocity (Vm) is:
\[ Vm = \sqrt{\frac{G}{d}} \]
Where:
Let's say the shear modulus (G) is 30,000,000 Pa, and the density of the material (d) is 2500 kg/m³. Using the formula:
\[ Vm = \sqrt{\frac{30,000,000}{2500}} \]
We get:
\[ Vm \approx 109.54 \, \text{m/s} \]
So, the material velocity is approximately 109.54 m/s.
