Hello, I was just wondering if an Impulse was exerted by one body on another if they collided but remained in total contact post-collision. The reason I ask is because my little I=F(delta)t indicates that there should be a change in time to calculate an impulse but in this case the 2 bodies are stuck together forever (so time change is 0 or infinite or something?) The example I had in my head was GSP vs Matt Hughes: They rush each other and upon collision, morph into one body...can you calc. the Impulse of GSP on Hughes? Thanks for your consideration.
