The position of the particle when it changes direction is x = 3.0 m
Explanation:
The position of the particle is given by the equation
In order to determine its position when it changes direction, we need to find the time t at which the velocity of the particle becomes zero.
The velocity of the particle si given by the derivative of the position, therefore:
The velocity is zero when:
And therefore, the position at t = 0.41 s is
