I need some help explaining these concepts 1. Suppose a tank is able to point its barrel up at an angle of 90o. If the tank is in motion and fires a shell straight up, where will the shell land if the tank maintains a constant motion. (don't consider any air resistance) a) in front of the tank b) behind the tank c) on top of the tank 2. Suppose an airplane drops a package out of its cargo hold while it is travelling through the sky with a constant horizontal speed. Where will the package land once it hits the ground? a) directly below the plane b) below the plane and ahead of it c) below the plane and behind it My explanations 1. C. Because the shell does not accelerate in the x-direction and... (i'm lost here) 2. A. (Not sure why, intuitively I can see why it happens but cannot explain why) Thanks.
