Question

The equation of motion of a particle is s=t^3−3t, where s is in meters and t is in seconds. Assuming that t≥0, answer the following questions.
1.) Find the acceleration when the velocity is 0.

anonymous · Answer

i have the velocity function as 3t^2-3 and the acceleration as 6t. I know those are both right

anonymous · Answer

Set your function of velocity equal to zero, and solve for t

anonymous · Answer

using the acceleration formula?

anonymous · Answer

the velocity.  

$$\frac{ ds }{ dt } = v = 0 = 3t^{2}-3$$

anonymous · Answer

Then you can solve for t, and use that t in your acceleration formula

anonymous · Answer

i have the velocity and acceleration equations

anonymous · Answer

ok

anonymous · Answer

does that make sense why you do that?

anonymous · Answer

yup. thanks i got it

anonymous · Answer

yay :)
