Can an object of a very large mass that is moving at a very slow speed hurt you?
momentum = mass x velocity
a bullet has very small mass, but has very high velocity, so it balances out and has a high momentum, and when it hits you, it hurts
a car has a reasonable mass, and a reasonable velocity, so it has a high momentum as well, and when it hits you, it hurts
but say i had like an extremely massive object, like lets say we just had some cube that had 99999999 kg, and then it moved at 0.001 m/s and touched me, it has a very large momentum still, but would it hurt?
following the other examples logic, it should, but i find it hard to imagine something moving that slow could hurt you

Suppose an elephant sits down on you very slowly. Would it hurt when you are flattered like a pancake?

Trash compactor scene in Star Wars. If it's slow enough you'd be fine as long as there was a place for you to go away from it.

No. As long as you were free to move it would just be an INELASTIC COLLISION. It would just push you. If you were standing against a wall, you would get crushed.

No. Lets say a train that weights 100,000 tons is moving at 3 mph and hits you. You will just move with it with no damage. That is because it is the DIFFERENCE in movement at causes the damage. The train easily overcomes your inertia an moves you out of the way.
