What is range of projectile?

Uzair said:   1 decade ago
Range of projectile is the maximum distance which it will cover. It is maximum at 45 degrees.

Sourabh raghuwanshi said:   1 decade ago
The range of projection can be found as:

R = u^2*sin2$/g ; where u = launch velocity ; $ : angle of projection from horizontal ; g : acceleration due to gravity.

Hence put $ = 45 degree.

Ya its 60 degrees, at 45 a projectile will attains maximum height.

Ye, 45' Angle of projection is correct.

Agree, 45 is the correct answer.

Mohan Krishna said:   8 years ago
Range=(2*u*sin(2*$))/g;
u=initial velocity.
$=angle.
g=acceleration due to gravity.

Yes, @45° the range will be maximum.

Aabid Ali said:   7 years ago
Yes, 45° is the correct answer.

Yes, at 90 it would be lowest at 30 it would be steepest at 45 it would be correct.
