Q3
A single conservative $$f\left(x\right)$$ acts on a $$m=1kg$$ particle moving along the x-axis. The potential energy $$U_{\left(x\right)}$$ is given by $$U_{\left(x\right)}=20+\left(x-2\right)^{2}$$ where $$x$$ is in metres. At $$x=5m$$, a particle has kinetic energy of $$20J$$.
The maximum value of potential energy is
