Answer:
(a) Projectile B will travel 4 times as far as projectile A prior to landing
Explanation:
Initial velocity = v
Angle at which the projectile is shot at = θ
g = Acceleration due to gravity
Range of a projectile is given by

When Initial velocity = v

When Initial velocity = 2v

Dividing the equtions, we get

Here, the angle at which the projectiles are fired at are equal.

Hence, projectile B will travel 4 times as far as projectile A prior to landing
