In a women's 100 -m race, accelerating uniformly, Laura takes 3.00 s and Healan 4.00 s to attain their maximum speeds, which they each maintain for the rest of the race. They cross the finish line simultaneously, both setting a world record of 10.5 s. (a) What is the acceleration of each sprinter? (b) What are their respective maximum speeds? (c) Which sprinter is ahead at the 6.00 -s mark, and by how much? (d) What is the maximum distance by which Healan is behind Laura, and at what time does that occur?

a parachutist opens his chute at time t=0, while falling vertically at a speed of 50.0 m/s.
