Answer:
Walking into a brick wall at normal walking speed (1.4 m/s), you will come to a complete stop in a short time (0.1 s) and experience much more acceleration (14 m/s²) back the way you came, but because you are softer than the wall, the inelastic collision will probably cause you to bounce back off the wall, changing the actual experienced acceleration you feel.
Explanation:
Assuming normal human walking speeds and time it takes to come to rest.
Normal human walking speed = 5km/h = 1.4 m/s
Time it takes you to come to a complete stop = 0.1 seconds
acceleration = Δ Velocity/ Time
Δ Velocity = final velocity - initial velocity
Δ Velocity = (1.4 - 0)m/s = 1.4 m/s
acceleration = 1.4/0.1
acceleration = 14 m/s²
Walking into a brick wall at normal walking speed, you will experience much more acceleration back the way you came, but because you are softer than the wall, the inelastic collision will probably cause you to bounce back off the wall, changing the actual experienced acceleration you feel.
Acceleration of the subject.
The acceleration is the rate at which the body velocity changes with time. It can be referred to the body the speed and direction. The point of the object moves in the straight line as acceleration is both a magnitude and a direction. Estimated acceleration of the subject and yourself
thus the answer is 1.4 m/s and stops at 0.1s
