How is the horziontal component of velocity for a projectile affected by the vertical component?
an airplane encounters a wind that blows in a perpendicular direction to the dirction its nose is pointing.Does the effect of this wind increase or decrease speed across the ground below?Or does it have no effect on ground speed?
