A player can throw a ball vertically upwards to a maximum height of 20 m . What is the maximum horizontal distance the player can throw the same ball?

Step-by-step solution

The maximum vertical height a person can throw a ball is achieved when the ball is thrown vertically upwards ( = 90^ ). H_ = u^2 2g = 20 m u^2 g = 40 m The maximum horizontal range is achieved when the ball is thrown at an angle of 45^ . R_ = u^2 g Substituting the value of u^2 g , we get: R_ = 40 m Answer: 40 m
