A particle moves along the xaxis so that at any time t ≥ 0, its position is given by x(t) = t3 − 12t2 + 36t. For what values of t is the particle at rest?

Best ResponseYou've already chosen the best response.1well for a particle to be at rest, doesn't it mean that the velocity of the particle is zero..?

Best ResponseYou've already chosen the best response.0So I should graph the equation and find the points where x=0?

Best ResponseYou've already chosen the best response.0I got that at (0,0) and (6,0) so my answer is 6 only because 0 and 6 is not an option

Best ResponseYou've already chosen the best response.0Actually it's at the maximums and minimums so 2 and 6

Best ResponseYou've already chosen the best response.1no, you need to find the velocity equation... which is the 1st dervative of displacement then solve for t, this is when the particle is stationary
