A nkcschools.instructure.com Near the surface of any planet, the distance D fallen by a rock in time t is given by D = ct(this is a consequence of Newton's 2nd law of gravitation). Here we will measure D in feet and t in seconds. (a) A rock is dropped from two different heights. It takes the rock 5 times as long to hit the ground from the taller height. How do the heights compare? The taller height is times as tall as the other. (b) On Venus, a rock dropped from 70 feet above the surface takes 2.2 seconds to strike the ground. What is the value of c for Venus? Round your answer to 2 decimal places. (c) Another rock is dropped on Venus. How far has it fallen after 4 seconds? Round your answer to 2 decimal places and include an appropriate label.

ct(this is a consequence of Newton's 2nd law of gravitation). Here we will
D =
measure D in feet and t in seconds.
(a) A rock is dropped from two different heights. It takes the rock 5 times as long to hit
the ground from the taller height. How do the heights compare? The taller height is
times as tall as the other.
(b) On Venus, a rock dropped from 70 feet above the surface takes 2.2 seconds to
strike the ground. What is the value of c for Venus? Round your answer to 2 decimal
places.
(c) Another rock is dropped on Venus. How far has it fallen after 4 seconds? Round
your answer to 2 decimal places and include an appropriate label.
