The horizontal range and maximum height attained by a projectile … - Vidyadip

MCQ

The horizontal range and maximum height attained by a projectile are $R$ and $H$, respectively. If a constant horizontal acceleration $a=g / 4$ is imparted to the projectile due to wind, then its horizontal range and maximum height will be

A
$(R+H), \frac{H}{2}$
B
$\left(R+\frac{H}{2}\right), 2 H$
C
$( R +2 H ), H$
✓
$(R+H), H$

✓

Answer

Correct option: D.

$(R+H), H$

d
(d)

$H=H$ (as vertical component of acceleration has not changed)

$R^{\prime} =u_x T+\frac{1}{2} a_x T^2$

$=R+\frac{1}{2} \times \frac{g}{4} \times \frac{4 u^2 \sin ^2 \theta}{g^2}$

$=R \frac{u^2 \sin ^2 \theta}{2 g}=(R+H)$
