One fielder throws a ball and in 4 seconds it reaches to another player. So, the maximum height reached by the ball above the point of projection would be about:
Correct answer: D. 20 m
- A. 10 m
- B. 7.5 m
- C. 5 m
- D. 20 m
Explanation
The correct answer is 20 meters. This can be calculated using the appropriate equations for projectile motion and considering the time taken for the ball to reach the other player. The other options are incorrect as they do not align with the calculated maximum height.

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.
