Can someone please help me, anything you can answer would be so helpful it is due today, please help, tysm 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? (4 points)
2. What is the magnitude of their final momentum? (3 points)
3. What is the magnitude of the impulse of the collision? (3 points)

Please don't answer with a weird link because I wont click on it so don't take up a potentially helpful answer by putting some useless scam thanks!
