The position of a particle moving along the x-axis is given by x = 3.49t2 – 2.21t3, where x is in meters and t is in seconds. What is the position of the particle when it achieves its maximum speed in the positive x-direction?

  • PHYS�CS -

    take the derivative of position to get speed. Then take the derivative of speed, set to zero, and find t for the max speed. Then put that t into the position equation.
