Question

The maximum range of a gun on horizontal terrain is 16 km. If g = 10m/$s^2$. What must be the muzzle velocity of the shell

• A. 200 m/s
• B. 400 m/s
• C. 100 m/s
• D. 50 m/s

Answer 1

The correct option is B

400 m/s

$R_{max}$ = $\frac{u^2}{g}$ = 16 $\times$${10}^3$$\Rightarrow$ u = 400m/s
