In the 1950’s, an experimental train that had
a mass of 36700 kg was powered across a level
track by a jet engine that produced a thrust
of 4.67×10^5
N for a distance of 528 m.
Find the work done on the train.
Answer in units of J.
mass has nothing to do with this
work = force * distance in direction of force
= 4.67 * 10^5 * 528 Joules
To find the work done on the train, we can use the formula:
Work = Force × Distance
In this case, the force applied is the thrust produced by the jet engine, which is 4.67×10^5 N. The distance traveled by the train is 528 m.
Substituting these values into the formula, we get:
Work = (4.67×10^5 N) × (528 m)
To compute this, we multiply the two values together:
Work = 2.46696×10^8 N·m
However, the units for work are joules (J), which are equivalent to N·m. So the work done on the train is equal to:
Work = 2.46696×10^8 J
Therefore, the work done on the train is approximately 2.46696×10^8 joules (J).
