Question

A boy can throw a stone up to a maximum height of 10 m. The maximum horizontal distance that the boy can throw the same stone up to will be : (A) 20√2 m (B) 10 m (C) 10√2 m (D) 20m

For vertically projected up body maximum height

(H)

is given as

H = \frac{u ^{2}}{( 2 g )}

For the same bocy with same initial velocity the horizontal distance traveled when thrown at an

angle (θ)

is given as

R = \frac{u ^{2}}{g} .

Compare equations 1 and 2

R = 2 H R = 2 \times 10 R = 20 m

Q. A boy can throw a stone up to a maximum height of $10 m$ . The maximum horizontal distance that the boy can throw the same stone up to will be :

$202 m$

$10 m$

$102 m$

$20 m$
