If R is the maximum horizontal range of a projectile, then the greatest height attained by it is
Correct answer: C. R/2
- A. R
- B. 2R
- C. R/2
- D. R/4
Explanation
(c) R/2 (Correct): This is the correct answer. For a projectile launched at an angle of 45 degrees (which maximizes the horizontal range), the maximum height (H) can be estimated as:H = R/2This relationship can be derived using the equations for the horizontal range and maximum height of a projectile, considering specific values for the launch angle and initial velocityIncorrect Options Explanation:a) R (Incorrect): While the maximum horizontal range (R) and maximum height (H) are related, they are not equal. Generally, the maximum height is less than the horizontal range.(b) 2R (Incorrect): This value is too high compared to the typical relationship between R and H for a projectile.d) R/4 (Incorrect): This value is too low compared to the typical relationship between R and H. The maximum height is usually closer to half the horizontal range, not a quarter.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
