a small stone is dropped from the top of a building and strikes the ground 2 seconds later.
a) determine the height of the building and velocity of the when the stone strikes the ground.
b) the same stone is dropped from a different building and takes 4 seconds to land on the ground. Determine the height of the building and the velocity of the stone when the stone strikes the ground.
c) compare the impact speeds for these two stones. how much faster is the second stone at impact? can you explain why it is this much faster?
d) compare the distances traveled by these two stones. how much farther does the second stone travel?
