Question

What is Emmy's velocity at a time of 3.73 s?

Answer 1

Below

Step-by-step explanation:

From the top graph her acceleration is -3 m/s^2 at the point in question

From the lower graph at time t = 3 s her velocity = 5 m/s

vf = vo + at

= 5 m/s + (-3)(.73) <====3.73 s is .73 s past the 3 s mark

= 2.81 m/s
