Question

A particle is moving along the x-axis so that its position at t ≥ 0 is given by s(t) = (t)In(3t). Find the acceleration of the particle when the velocity is first zero.

Answer 1

Use the product rule to take the derivative of s(t) and get v(t). Then take the derivative of v(t) to get a(t)

Answer 2

thanks thats 100% useless i already knew that

Answer 3

I'd think if you already knew it, you'd do it. You posted a question, gave no evidence of an attempt, didn't say anything about where you were stuck, and went offline. What kind of response did you expect with zero effort on your part?
