Train problem
005 (part 1 of 1) 10 points
A 23-car train standing on the siding is started
in motion by the train's engine. There are
4 cm of slack between cars. The cars are 9 m
long. The engine is tightly connected to the
first car and moves at a constant speed of
22 cm/s.
How much time is required for the pulse to
travel the length of the train? Answer in units
of s.
i used the t = d/v
i calculated the distance of the train to be 9m * 23 cars + 4cm slack* 22 cars slack is between = Distance and then converted to cm
and used the Velocity as 22 cm/s
and solved for T
is this the correct approach
