    Catapult Question

    Hi,

    I created a working catapult model and I was wondering , if I launched multiple marbles using the same force and the same launching angle of 80 , does that mean that all projectiles will have the same maximum height? I believe yes because you can not possibly go beyond the launch angle because there are no other forces lifting the projectile.

    If all marbles have the same mass, then, yes, same force and mass with give same initial velocity and, with same launching angle, same initial vertical velocity.

    Re: Catapult Question

    Applying the same force to a greater mass will result in a smaller acceleration so a lower speed when the ball is released from the catapult. The result would be a lower height.

    Masses also show up as part of air resistance if you are considering this as part of the problem.

    Re: Catapult Question

    Odds are, if you launch multiple balls at once then they will collide, and none of them will reach their potential maximum heights
