thermodynamics?
1. A force F measured in the x direction is given as F=a/x^2 where the constant a = 9 N m^2. Find the work in joules as F moves from x1= 1m to x2= 3m.
2. The force in newtons required to stretch a spring beyond its free length is given try F=200x where x is in meters. Find the force and work required to stretch the spring 0.1 m; 0.5 m; 1m.
1.
F=9/x^2.
as the force is variable,u need to integraete 9/x^2 between the limits x=1 to x=3 to get the required work done.
work done=6joule.It is to be done by integrating as work done is :integral(force.distance)
2.force can be calculated by directly applying the formula F=200x.the work done again has to b calcualted by integrating 200x btween limits whr work has to be calculated
