A cricketer throws a ball up to a horizontal distance of 150 meters. If he throws the ball vertically upwards with the same effort then, what will be the maximum height projected by the ball?
Correct answer: B. 75 m
- A. 100 m
- B. 75 m
- C. 50 m
- D. 150 m
Explanation
When a ball is thrown vertically upwards, the maximum height it reaches can be calculated using the equation h = v₀² / (2g), where v₀ is the initial velocity and g is the acceleration due to gravity. In this case, the maximum height projected by the ball when thrown vertically upwards is 75 meters. Options A, C, and D are incorrect as they do not consider the correct formula for calculating the maximum height of a projectile thrown vertically upwards.

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.
