Question

A position vs. time graph of a frog swimming across a pond has two distinct straight-line sections. The slope of the first section is 1 m/s. The slope of the second section is 0 m/s. If each section lasts 1 second, then what is the frog’s total average velocity?

a) 0.5 m/s

b) 1.0 m/s

c) 1.5 m/s

d) 2.0 m/s

Answer 1

The frog's total average velocity is 1 m/s.

Step-by-step explanation:

The frog's total average velocity can be calculated by finding the average velocity of each section and then summing them.

The average velocity of the first section with a slope of 1 m/s is also 1 m/s because the slope of a position vs. time graph gives the velocity.

The average velocity of the second section with a slope of 0 m/s is 0 m/s. Therefore, the frog's total average velocity would be 1 m/s + 0 m/s = 1 m/s.
