Question
Freight trains can produce only relatively small acceleration and decelerations.
Hint
a. What is the final velocity of a freight train that accelerates at a rate of 0.03 m/s² for 8.0 minutes,
starting with an initial velocity of 3.65 m/s.
Its final velocity is
b. If the train can slow down at a rate of 0.60 m/s², how long, in seconds, will it take to come to a stop
from this velocity (i.e., 3.65 m/s)?
It will take
c. How far in meters will it travel during acceleration?
It will travel
m/s.
s to come to a stop.
m during acceleration.
d. How far in meters will it travel during deceleration?(Hint: take the final velocity to be zero and use
the initial velocity given in the problem i.e., 3.65 m/s).
It will travel
m during deceleration.
