How do I make an object fall and sink into the ground?

so i'm making a game similar to trap adventure and i'm trying to make it so that spikes fall from the ceiling and sink into the ground, but i cant seem to know how to make it sink. please help me fix this problem in my game!

What is your logic for the spikes when falling on the ground?

If you use bullet, then you could do it like this:

Spike on collision with ground -> Set bullet speed to 10.

You could add a timer and Start it for 2-3 seconds when Spike collide with the ground.

Then add an event with the timer where you destroy the spike.

i'm using physics or my falling spikes, and i got them to fall, but now when you die, the spikes don't reset, and there are no more spikes, or they reset at weird angle, and don't fall right.

i just fixed it thank you
