The potential energy of a 1 kg particle free to move along the x -axis is given by
The total mechanical energy of the particle 2 J. Then, the maximum speed (in m/s) is
As we learnt in
If only conservative forces act on a system, total mechnical energy remains constant -
First we neet to calculate minimum potential energy.
When potential energy is minimum
V(x = 0) = 0
So minimum potential energy
K.E. + P.E. = Total mechanical energy.
