A missile is fired for maximum range with an initial velocity of `20m//s`. If `g=10m//s^(2)`, the range of the missile is

A

20 m/sec

B

40 m

C

50 m

D

60 m

Text Solution

Verified by Experts

The correct Answer is:
B
`R = u^(2)/g = (20)^(2)/10 = 400/10 = 40 m [therefore (sin 2theta)_("max") = 1]`
