8.)The graph below shows a beetle’s
7.) The graph below illustrates the position and
time for a dog that runs to catch a stick and
movement along a plant stem.
then returns with it.
During which span of time was the beetle not
moving?
A. from 0 to 4 minutes
The dog caught the stick after 2 s. What was
B. from 4 to 6 minutes
the dog’s average speed as he returned with the
C. from 6 to 14 minutes
stick?
D. from 14 to 16 minutes
A. His average return speed was 0.7 m/s.
B. His average return speed was 0.9 m/s.
C. His average return speed was 2 m/s.
D. His average return speed was 4 m/s.
My Answer and Explanation:
My Answer and Explanation:
B. The dog ran back 7 m in 8 s (the
C. A horizontal line on a distance versus
time from 2 s to 10 s). Speed = d / t
time graph represents “not moving”
= 7 m / 8 s = ~0.9 m/s
since it is a slope of zero. The position is
not changing and the beetle has a speed
of 0m/s.
