8. On Mars, a 15 N (as measured on Mars) vase is dropped out of an apartment window from a height of 40 m onto the cement sidewalk below. When it reaches the pavement, it stops over a distance of 0.5 cm (0.005 m). [Assume: ● ● ● constant acceleration as it fell in free fall and a different constant acceleration as it was stopping. Air resistance is negliglible. Down is positive (+) The vase does not bounce on the pavement.] (a) How much time did it take for the vase to reach the pavement? (b) How fast (speed) is the vase traveling just before it hits/touches the pavement? (c) What is the average velocity of the vase as it fell - from beginning to just before it hit the pavement?
