ignoring air resistance a projectiles vertical speed will what?

In the absence of air resistance, the only force acting on both objects would be gravity. Both objects would experience the same 9.8 m/s² acceleration toward the ground. Since the initial conditions of both projectiles are identical, the velocities of both projectiles will be the same at all times. Therefore, both projectiles will attain a zero vertical velocity at the same time, and it is at this point that they simultaneously reach their respective maximum heights. The maximum heights will not be the same, and they will differ by precisely the amount of height difference between the launch points.To understand more about air resistance -https://brainly.com/question/14409464?referrer=searchResults#SPJ1
