To calculate the terminal velocity of the ball, we can use the formula for terminal velocity (V_t) in the presence of drag:
\[ V_t = \sqrt{\frac{2mg}{\rho C_d A}} \]
Where:
- \(m\) is the mass of the object (in kg)
- \(g\) is the acceleration due to gravity (approximately \(9.81 , \text{m/s}^2\))
- \(\rho\) is the density of the fluid (air) (in kg/m³)
- \(C_d\) is the drag coefficient (dimensionless)
- \(A\) is the cross-sectional area (in m²)
Given:
- \(m = 0.15 , \text{kg}\)
- \(g = 9.81 , \text{m/s}^2\)
- \(\rho = 1.225 , \text{kg/m}^3\)
- \(C_d = 0.007\)
- \(A = 0.0026 , \text{m}^2\)
Now, substituting the values into the formula:
\[ V_t = \sqrt{\frac{2 \cdot 0.15 , \text{kg} \cdot 9.81 , \text{m/s}^2}{1.225 , \text{kg/m}^3 \cdot 0.007 \cdot 0.0026 , \text{m}^2}} \]
Calculating the numerator:
\[ \text{Numerator} = 2 \cdot 0.15 \cdot 9.81 = 2.943 , \text{kg m/s}^2 \]
Calculating the denominator:
\[ \text{Denominator} = 1.225 \cdot 0.007 \cdot 0.0026 = 0.0000213332 , \text{kg/m} \]
Now divide to find \(V_t\):
\[ V_t = \sqrt{\frac{2.943}{0.0000213332}} \approx \sqrt{138750} \approx 372.7 , \text{m/s} \]
However, considering the parameters may not match all criteria listed, let's slightly adjust the drag coefficient since 0.007 is exceptionally low for a ball. That said, the most appropriate calculations lead us close to expected terminal velocities.
Nevertheless, without further adjustments or parameters affecting from drag coefficient adjustments in your options, the closest response (given previous calculation variations) might suggest:
The calculated terminal velocity is approximately 363 m/s.
