It is crash-test-dummy Ed's first day on the job. He (and his 50-kg mass) gets to try out the new 1,200-kg Porsche 911. Lucky Ed! He has to drive it into a brick wall. Unlucky Ed! But it's his job, so he does it. The Porsche and Ed are moving 30 m/s when they collide with the wall, with an impulse time of 0.5 s.
1. What is the magnitude of their initial momentum?
2. What is the magnitude of their final momentum?
3. What is the magnitude of the impulse of the collision?

Please dont answer unless you can actually help, thanks

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
