JEE Main 2023 Physics question on Kinematics

The maximum vertical height to which a man can throw a ball is 136 m. The maximum horizontal distance upto which he can throw the same ball is:
  1. A.
    192 m
  2. B.
    272 m
  3. C.
    136 m
  4. D.
    68 m
Show answer and solution

Correct option: B

Solution

When throwing for maximum height, all initial velocity is directed vertically: u² = 2g×136, giving u² = 2×10×136 = 2720 m²/s².

For maximum horizontal range, the ball is launched at 45°, giving R = u²/g = 2720/10 = 272 m.
