The position of a particle moving along the xaxis 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 xdirection?

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.

ý don't know how to do it. ý need only answer... no more...
