The maximum range of a gun of horizontal terrain is 16 km. If g = 10 mis, then the muzzle velocity of a shell must be

A

`200sqrt2 m//s`

B

`160 m//s`

C

`800 m//s`

D

`400 m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
The maximum range
`R = u^2/g`
`16 xx 10^3 = u^2 /10`
`u^2 = 16 xx 10^4,u =400 m//s`

A gun is mounted on a stationary rail road car. The mass of the car, the gun, the shells and the operator is 50 m, where m is the mass of one shell. Two shells are fired one after the other along same horizontal line in same direction. If the muzzle velocity of the shells is 200 m/s, then find the speed of the car after second shot.
