34. Which of the following statements about a projectile is not correct? A.
- A. A projectile motion is a two-dimensional motion.
- B. A projectile is an object launched into air and allowed to move freely due to gravity.
- C. The range of the projectile is independent of the acceleration due to gravity.Correct
- D. The time of flight is dependent on the acceleration due to gravity.
Explanation
The time to reach maximum height, the maximum height reached, the time of flight and the range all depend on the initial velocity, the angle of projection and the acceleration due to gravity. This is evident in their formulae, e.g. R=u^2sin(2theta)/g.
