Question

'If 'θ' is angle of projection and 'u' is velocity of projection for a projectile, then its horizontal
range is given by-

R = (u^2 sin2θ) / g

R = (u^2 cosθ) / g

R = (u^2 cos2θ) / g

R = (u^2 sinθ) / g

Solution

Correct option is A

The horizontal range of a projectile is given by the formula:

Where:
u is the initial velocity of projection,
θ is the angle of projection,
g is the acceleration due to gravity.
This formula calculates the horizontal distance traveled by the projectile when it returns to the same height from which it was launched.
