- Question about pushing a ship
If you push a floating object from land, the object should move away.
If you push a floating object from the floating object, the force should be equal and opposite, and floating object won't move.
What if you push a floating object from a ramp, where the ramp is connected to the floating object but also resting on the shore?
Think of a roll-on roll off-ferry, where vehicles drive on to the ferry via a ramp. But imagine there is a closed door at the top of the ramp and a car is on the ramp pushing against the closed door. (Ignore momentum and inertia - ie assume the car gently rests against the door before increasing force gradually and that the force is enough to over come the ship's inertia)
