Transcribed Image Text:Judith is overseeing the setting up a dangerous stunt for a movie. The script calls for two trains
to travel towards each other at 20 m/s to the right and 20 m/s to the left. The rightwards moving train
can slow down with an acceleration of 1 m/s² while the leftwards moving train is limited to a
deceleration of 0.5 m/s². The trains will both start to slow down a distance of 800 meters from each
other. Without using any equations, Judith predicts that the trains will stop nose to nose 200 meters
from the right, and 600 meters from the left.
these are numbers you want to compare
Is Judith correct about the stopping locations of both trains?
a possible goal for this one, is to to calculate
the stopping distance of both trains and
compare it to the 200 and 600
