AP Physics C: Mechanics
1.2 Displacement, Velocity, and Acceleration
An automated test cart moves along a straight horizontal track such that its position as a function of time is given by \(x(t) = 2t^3 - 6t^2 + 5\), where \(x\) is in meters and \(t\) is in seconds. What is the acceleration of the cart at the instant \(t > 0\) when its velocity is momentarily zero?
