help with knowing how to calculate expected value, and standard deviations. thank you

the set up is:

a particle moves along the x-axis in such a way that at time t>0 its position coordinate is x= sin (e^t)

so now the question is: at what time does the particle first have zero velocity?

i know you have to take the derivative of the position function given to get velocity and i got: v= cos (e^t)(e^t)dt, is this right? if so, then how would you find at what time the particle has a zero velocity?

thanks!
