the position function x(t) of a particle moving along an x axis is x=4.0-6.0t^2, with x meters and t in seconds. (a) at what time and (b) where does the particle (momentarily)stop?
i made x=0
and i made the equation equal this t=sqrt(4.0/6 = .8164995809
i put it into the equation and x=0
is this correct. I'm assuming that the particle is zero meters when it stops
but what do i know i'm not an expert
