Compute each part of given question:
Question: Suppose you run into a wall at 4.5 meters per second (about 10 mph). Let's say the wall brings you to a complete stop in 0.5 second.
Part A: Find your deceleration?
Part B: Estimate the force (in Newton's) that the wall exerted on you during the stopping.
Include work and exact answer please! Thanks!
