Now I'm taking the integral of a but when I plug in the other parts, it doesn't work out. I think I'm doing something wrong.

Someone please comment on how-to approach this problem step by step thanks!

[tex]a(t)= \frac{d(s')}{dt} =4s^2[/tex]

Move over dt integrate, set the limits, and solve.

What dynamics book are you using? There should be a problem similar to this given somewhere as an example.

after moving over dt to integrate, how did you approach it from there

Type out what you got and what you did.

You can use [tex] and [ / tex] tags to make it look nicer.

s=10

4(10^3)/3 = 1333.33

1333.33/10 = 133.33 = particle velocity at x position

Are you familiar with the definition of acceleration?

Which class is this HW for?

I think you need to solidify the fundamentals before doing this HW. You should know better that acceleration is the second derivative of position by now.

I can point out mistakes, but im not going to teach you fundamentals.

also acceleration is the rate at which a object increases/changes its velocity(speed)

What you need to do: set up your limits of integration.

Do you know what limits of integration are?

yes integral from one value to another

so what are your value you used?

0 to 10.............

What happened to the limits on the integral of the velocity?

-100x? that one?
