Impact is change momentum, or delta Velocity*mass. Dont they have the same change of velocity, and the same mass?

Denke.

Yeah, so therefor it is the same impulse?

but J = FT
The force is the same but the T interaction is different? or something?

If time of contact is different, then the forces are different. But implulse is the same.
