Question

The position function x(t) of a particle moving along an x axis is x = 4.00 -6.00t², with x in meters and t in seconds. At what time the particle (momentarily) stop?

Answer 1

t = 0 seconds

Step-by-step explanation:

in order for the particle to momentarily stop, the slope on the position function should be equal to zero somewhere. the slope is only zero at t = 0 seconds.
