23. A particle moves along a line with velocity function y(t) = t - t. Find (a) the displacement and (b) the distance traveled by the particle during the time interval (0,5). 24. A heavy-duty spring with spring constant k = 10,000 N/m is used to cushion the shock of a subway car at the end of the line in the event it does not come to a complete stop before bumping the end. Find the work done by the force of the subway car if in bumping the end, the spring is compressed a distance of 1 m. 25. Find the volume of the solid generated by revolving the region bounded by y=x", 1 = 0, and y = 8 about the z-axis.
