A missile is fired for a maximum range with an initial velocity of 20 m/s, the range of a missile is

[NEET-2011]

a. 40m b. 50m c. 60m d. 20m

The range of a projectile can be given as

Where,

'u' is a velocity of projection

The maximum range can be achieve when the angle of projection will be 45 degrees.

Also,

sin (2×45) = sin 90= 1

Therefore, above equation becomes,

Putting values we get,

i.e. the range of the missile will be 40 m
