1) Horizontal range is directly proportional to the square of the speed. If the speed of A is doubled, horizontal range will increase 4 times. Hence the new ratio of horizontal range will be 12 : 1.
2) Let at any instant, the particle is at P and velocity is y.
ux = u cos θ uy = u sin θ
ax = 0 ay = -g
yx = ux + axt yy = ux + axt
yx = u cos θ yy = u sin θ - gt
The velocity of projectile,
