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
