Hi Sonia! I put a modulus sign at the back just in case the integral gets a negative number (which turns out to be the case), since distances can only be positive numbers).
Let me know if my workings are unclear and I will explain them to you.

Hi Eric, substituting v = 0 to find t when particle is instantaneously at rest, by mistake dropped the negative sign in
v = 40[ e^(-t) - 0.1 ] ?
Don't have pen and paper right now, t should be ln 10?
v = 40[ e^(-t) - 0.1 ] ?
Don't have pen and paper right now, t should be ln 10?
Whoops...will redo them later. Dropped the negative by accident. Thank you!
Yup it’s ln 10 (since 0.1 is the reciprocal of 10).
Thanks for your dedication towards tutoring on the app!
No worries
