A body is projected with an initial velocity 'u' at an angle to the horizontal. If Rmax is the maximum range of the projectile, what does u²/Rmax represent?
- A. the vertical distance covered
- B. acceleration due to gravityCorrect
- C. the horizontal distance covered
- D. the acceleration of the body
Explanation
At maximum range (θ=45°), Rmax = u²/g, so u²/Rmax = g, the acceleration due to gravity.
