In the 1950’s, an experimental train that had a mass of 41000 kg was powered across a level track by a jet engine that produced a thrust of 5.89 × 105 N for a distance of 520 m.
Find the work done on the train.
Answer in units of J.
W = Fd = 5.89*10^5 * 520 = 30.63*10^7J.
To find the work done on the train, we can use the formula:
Work = Force × Distance
In this case, the force exerted on the train is the thrust produced by the jet engine, which is 5.89 × 10^5 N, and the distance traveled by the train is 520 m.
Plugging in the values into the formula:
Work = (5.89 × 10^5 N) × (520 m)
Calculating this:
Work = 3.0578 × 10^8 N·m
Since the unit for work is Joules (J), we need to convert N·m to J. Since 1 J = 1 N·m, the work done on the train is:
Work = 3.0578 × 10^8 J
Therefore, the work done on the train is approximately 3.0578 × 10^8 J.
