A person can throw a stone to a maximum distance of 100m.the greatest height to which he can throw the stone is?

Answer 1

the simplified range equation is
... Rmax = v² / g ... 100 = v² / g
... 100 g = v²

when an object is thrown straight up, the initial kinetic energy becomes gravitational potential energy
... ½ m v² = m g h ... v² / (2 g) = h

combining the two formulas
... (100 g) / (2 g) = h
... 50 = h
