Estimate the acceleration you subject yourself to if you walk into a brick wall at a normal walking speed.? - brick wall estimate
Estimate is subject to acceleration if you walk into a wall at normal walking speed. (Make a reasonable estimate of the velocity and the time it needs to be to make one stop and explain the numbers.)

Brick Wall Estimate Estimate The Acceleration You Subject Yourself To If You Walk Into A Brick Wall At A Normal Walking Speed.?

That depends on a rule, how fast you walk - and you think the wall is a solid object (well, it is a plastic deformation infinitessimally always in the moment of impact, but we ...) experienced an inelastic collision, and can (a total standstill in about the same amount of time, a difference of a few nanoseconds if you run into the wall at 3 km / h to mph faster than 3.5 hours, but it is insignificant in a calendar that you can know ) So let's say the average walking speed of 3 mph (for simplicity) and make a stop in about 0.1 seconds. Let's in terms of acceleration m / sec / sec, 3 mph and feet/3600 x 5280 sec / h / 0.1 seconds = about 44 m / sec / sec acceleration in the opposite direction. Traveling at higher speed, acceleration come a long way over the way you are, but because they are softer than the wall, the inelastic collision is likely bounce off the walls, change the acceleration feels real. Difficult to answer, in fact, without Morand assumptions.
when I went into the wall, not accelerated.
