#10) A dump truck fully loaded weighs 74,000.0 pounds (33.6x10³ kg). The dump truck is initially at rest
on a horizontal surface. The dump truck then starts moving at its maximum constant acceleration of 0.150
m/s². The dump truck accelerates for 25.0 seconds then starts to coast. When coasting, the dump truck
decelerates at a rate of 0.225 m/s². Use the initial direction of motion of the dump truck as the positive
direction in your coordinate system (report answers to 3 sig figs and show all work including starting
equations and algebra).
