A robot arm that controls the position of a
video camera in an automated surveillance
system is manipulated by a servo motor that
exerts a force on a push-rod.
The force is given by
F(x) = x2 ,
where x is the position of the end of the push-
If the push-rod moves from x1 = 0 m to
x2 = 17 m, how much work did the servo
Answer in units of J.
Note: F(x)=x^2 ……not x2
