Maximum range =(u2/g) 10 × 15000=u2 150000=u2 100 √15=387.2 m / s

Q. The maximum range of a gun on horizontal terrain is $15 km$ . If $g = 10 m / s^{2}$ . What must be the muzzle velocity of the shell?

$387.2 m / s$

$390 m / s$

$380 m / s$

$350 m / s$

Maximum range $= \frac{u ^{2}}{g}$
$10 \times 15000 = u^{2}$
$150000 = u^{2}$
$10015 = 387.2 m / s$
