A object of mass 3.00 kg is subject to a force *F*_{x} that varies with position as in the figure below.

If the object has a speed of 0.400 m/s at x=0

find its speed at x=5.00 m

and its speed at x=17.0 m

Step 1

Area under force-displacement graph will give the work done.

Area under graph from *x*=0 m to *x*=5 m is,

Step 2

According to work energy theorem, work done will equal to change in kinetic energy.

Step 3

Area under graph from *x*=0 m to *...*
