A cricketer can throw a ball to a maximum horizontal distance of 100 m. How much high above the ground can the cricketer throw the same ball?

Horizontal range is maximum if the angle of projection is 45°.

Horizontal range in this case is given by,

                straight R subscript max space equals space straight u squared over straight g

If the cricketer throws the ball vertically upward then it will attain the maximum height from the ground.

∴      straight H subscript max equals fraction numerator straight u squared over denominator 2 straight g end fraction equals 100 over 2 equals 50 straight m, is the height of the ball from the ground.
