Questions
A projectile can have same range from two angles of projection with same initial speed. If h1 and h2 be the maximum heights, then
a
R=h1h2
b
R=2h1h2
c
R=2h1h2
d
R=4h1h2
detailed solution
Correct option is D
R=u2sinθg at angles θ and 90°-θNow, h1=u2sin2θ2g and h2=u2sin290°-θ2g=u2cos2θ2gh1h2=u2sin2θg2·116=R216∴ R=4h1h2Talk to our academic expert!
