The greatest height to which a boy can throw a stone is (h). What will be the greatest distance on horizontal surface upto which the boy can throw the stone with the same speed ? Neglect the air friction.

Options

A. `(h)/(2)`
B. h
C. 2h
D. 3h

Answer

C

Explanation

Maximum height `(u^(2))/(2g) = h` (given)
Now, `R_(max) = (u^(2)sin 90^(@))/(g) = (u^(2))/(g) = 2h`
