The maximum range of gun on horizontal ...

The maximum range of gun on horizontal terrain is 15 km. If g = 10 `m//s^(2).` What
must be the muzzle velocity of the shell ?

A

387.2 m//s

B

390 m//s

C

380 m//s

D

350 m//s

Text Solution

Verified by Experts

The correct Answer is:
A
Maximum range = `(u^(2))/(g)`
`10 xx 15000=u^(2)`
150000 = `u^(2)`
`100 sqrt 15 = 387.2 " m/s"`
