The work done in moving an object along a straight line with (varying) force F = F(x)
from a point x1 to another point x2 is given by W =∫Fdx (limits are obviously from x1 to x2). The force applied to
a train as it starts out in Town A (x = 0) and runs for 20 000 metres (m) to Town
B along a straight train track, is F(x) = e^(−2x) − (x − 10 000)^2 + 100 000 000 Newtons
(N). What is the work done (in Joules) on the train as it moves from Town A to Town
B? Give your answer correct to 2 significant digits.
can anyone help?

Evaluate the integral of that function from 0 to 20,000
