In the 1950s, an experimental train that had a mass of 2.25 ✕ 104 kg was powered across a level track by a jet engine that produced a thrust of 4.75 ✕ 105 N for a distance of 509 m. Assume that air resistance is negligible.(a) Find the work done on the train.
Question
In the 1950s, an experimental train that had a mass of 2.25 ✕ 104 kg was powered across a level track by a jet engine that produced a thrust of 4.75 ✕ 105 N for a distance of 509 m. Assume that air resistance is negligible.(a) Find the work done on the train.
Solution
The work done on an object is given by the formula:
Work = Force x Distance
In this case, the force is the thrust produced by the jet engine, and the distance is the distance the train traveled.
So, we can substitute the given values into the formula:
Work = (4.75 x 10^5 N) x 509 m
Now, we just need to multiply these values together to find the work done on the train.
Work = 2.42 x 10^8 Joules
So, the work done on the train is 2.42 x 10^8 Joules.
