A person can throw a ball upto a maximum range of 100 m . How high above the ground he can throw the same ball?

Options

  1. A25   m
  2. B50   m
  3. C100   m
  4. D200   m

Correct answer

B. 50   m

Step-by-step solution

Horizontal range is maximum if the angle of projection is 45 ° and is given by R max = u 2 g Here, R m a x = 100   m Then, 100 = u 2 g     ⋯ 1 If the ball is thrown vertically upward, then the ball will attain the maximum height from the ground as H max = u 2 2 g H max = 100 2 = 50   m
