1. the space shuttle travels at speed of about 8.53 times 10 m/s. The blink of an astronaut's eye lasts about 160 ms. How many football fields (length = 91.4 m) does the space shuttle cover in the blink of an eye?

2.

For each of the three pairs of positions listed in the following table, determine the magnitude and direction (positive or negative} of the displacement Initial position .1", Final position .1' ta! + 1.63m + 6.45m lb} + 6.23m + 1.?9m [l'l 3.23m + 6.99m [all Displacement = Number Units v {b} Displacement = Number Units v [c] Displacement= Number Units v The data in the fol lowing table describe the initial and nal positions of a moving car.The elapsed time for each of the three pairs of positions listed in the table is 0.540 5. Review the concept of average velocity in Section 2.2 and then determine the average velocity {magnitude and direction} for each of the three pairs. Note that the algebraic sign of your answers will convey the direction.
