8. GO An 18-year-old runner can complete a 10.0-km course with an average speed of 4.39 m/s. A 50-year-old runner can cover the same dis- tance with an average speed of 4.27 m/s. How much later (in seconds) should the younger runner start in order to finish the course at the same time as the older runner?

3. You wake up in a strange room, with opaque walls, and no visible doors or windows. you drop a ball from a height of 1.50 m, and observe that it hits the floor 0.277 s after you drop it. In this case, you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 29.3 m/s^2 58.7 m/s^2 39.1 m/s^2 19.5 m/s^2

3. A bee flies in a straight line (a "beeline" as they say). The initial speed of the bee is Vo = 100 cm/s. The acceleration of the bee versus position is given by the graph below. a [cm/s²] 500 0 -250 50 105 145 195 s [cm] a. At what position will the speed of the bee be maximum? Hint: it will be one of the labeled points: 0cm, 50cm, 105cm, 145cm or 195cm. b. What is the speed of the bee at that location? C. What is the speed of the bee after traveling the full 195cm? Hints: you don't need to figure the equations for the four lines to do the integrals, and be careful of the signs.
