Question

The greatest height to which a man can throw a stone is h.The greatest distance to which he can throw will be

• A. h/2
• B. h
• C. 2 h
• D. 4 h

Answer 1

The correct option is C 2 h

Greatest height can be achieved only if he throws the stone in vertically upward direction give by $h=u^2/2g$ so $u^2=2gh$ ...... (1)

Range or horizontal distance is given as $R=u^{2}Sin2\theta /g$ which can be maximize if $Sin2\theta =1$ so maximum range becomes $R=u^2/g$

by putting the value of $h$ from equation-1 we get $R=2h$

Option c is correct.
