Questions  

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),H2
b
R+H2,2H
c
(R + 2H), H
d
(R + H), H

detailed solution

Correct option is D

H'=H    (as vertical component of acceleration has not changed)R=uxT+12axT2=R+12×g4×4u2sin2θg2=R+u2sin2θ2g=(R+H)
