SUMMARY
The discussion centers on the conditions for maximum speed of a particle P moving along the x-axis, defined by the velocity function V={8t-3/2t²} for the interval 0≤t≤4 and V={16-2t} for t>4. It is established that the acceleration must equal zero at the point of maximum velocity within the interval 0≤t≤4. This is visually supported by plotting the velocity versus time curve, which reveals that the maximum velocity occurs at the vertex of the downward-opening parabola, where the slope (acceleration) is zero.
