It is conservation of energy. Is there a particular part you want to ask about?

Use mg(h at L minus h at N)
This will be the loss of potential energy going from L to N which will be changed into Kinetic energy

What do u think resistance to motion means??

Look up resistance in the dictionary....then add no in front of definition.
What does assume mean?

Try explainin to urself then! hope it helps!  ;D
