v = 0.92 \cdot \sqrt{2 \cdot 9.8066m/s² \cdot 24mm + {(34m/s \cdot 0.611 \cdot \frac{4.4m²}{7.1m²})}^{2}}

Next Step Convert Units

∴

v = 0.92 \cdot \sqrt{2 \cdot 9.8066m/s² \cdot 0.024m + {(34m/s \cdot 0.611 \cdot \frac{4.4m²}{7.1m²})}^{2}}

Next Step Prepare to Evaluate

∴

v = 0.92 \cdot \sqrt{2 \cdot 9.8066 \cdot 0.024 + {(34 \cdot 0.611 \cdot \frac{4.4}{7.1})}^{2}}

Next Step Evaluate

∴

v = 11.8609131886333m/s

LAST Step Rounding Answer

∴

v = 11.8609m/s
