Question

What is the average velocity of a cat chasing a mouse that traveled 2,500 meters East in 40 seconds? What was the final velocity of the mouse if it started from rest with a acceleration of 2.5 m/s^2 during the same time period above? Show equations and work.

Answer 1

62.5 m/s East

100 m/s East

Step-by-step explanation:

Average velocity = displacement / time

v_avg = (2500 m East) / (40 s)

v_avg = 62.5 m/s East

Given for the mouse:

v₀ = 0 m/s

a = 2.5 m/s²

t = 40 s

Find: v

v = at + v₀

v = (2.5 m/s²) (40 s) + 0 m/s

v = 100 m/s East
