Worth 25 points on my exam
I am Lyosha [343]
  • Initial velocity=20m/s
  • Final velocity=0m/s(As the car stops)
  • Acceleration=-8m/s^2
  • Distance=s=26m

We need to verify the thrid equation of kinematics here

\\ \tt\longmapsto v^2-u^2=2as

\\ \tt\longmapsto 20^2=2(-8)s

\\ \tt\longmapsto 400=-16s

\\ \tt\longmapsto s=|400/-16|

\\ \tt\longmapsto s=25m

The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .
