21. when a ball is first dropped off a cliff in free fall, it has an
acceleration of 9.8 m/s2. what is its acceleration as it gets
closer to the ground? assume no air friction.
22. why is the position vs. time graph for an object in free fall a
curve?
23. draw a speed vs. time graph for an object accelerating from
rest at 2 m/s2.

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source.i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
