## Homework Statement

12.81[/B] A train traveling at 20m/s is brought to an emergency stop. During braking,

the acceleration is a=-(7/4)+(t/16) m/s^2, where t is the time in seconds measured

from when the brakes were applied. (a) Integrate the acceleration from t=0 to

t=16s using Euler's method with Δt=2s. (b) Use the results of the integration to

determine the stopping distance of the train and compare you answer with 138.7m,

the value found analytically.

**12.82**Solve Prob. 12.81 using the modified Euler method with Δt=4s

## Homework Equations

## The Attempt at a Solution

12.81 [/B]was handled in my previous post in this sub forum. I attach my attempt in

**12.82.**

I have run an online modified Euler calculator and my values are not correct.

Can you check this?
