An iceberg is a chunk of a glacier that has broken off and is floating in the ocean. Icebergs are made of fresh water while the ocean is salt water. The difference in the densities of fresh and salt water is minimal. Because of this, 90% of the iceberg is actually below the surface of the ocean water. As with an iceberg, there is more to tundra plants than what you see on the surface. Which statement below supports the analogy?

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
