Question
The maximum range of a gun horizontal terrain is 10km. if g = 10m/s2 what must be the muzzle velocity of the shell
Options
A.400 m/s
B.200 m/s
C.100 m/s
D.50 m/s
Solution
For maximum range
R =
⇒ u2 = gR
u2 - 16,000 × 10 ⇒ u = 4 × 100
u = 400m/ sec
R =
⇒ u2 = gRu2 - 16,000 × 10 ⇒ u = 4 × 100
u = 400m/ sec
