Read off values from your graph and subtract them for the relevant velocities. You should get positive answers as it says extra energy.
For ii) what form does the extra energy take?

Read what values and subtract them from what?
thanks !
The graph is imo a little irritating as I wold prefer the axes to be turned around. The table gives a velocity, so read across and find the predicted energy from the equation (dotted line) and the actual energy (curved line). Then subtract them and make sure you get a positive result. Do that for each missing value in the table.
EDIT: your Y axis is btw, so you want to use the value from that column, not the one.

Can you explain the second part as well? Thanks !

You've calculated an amount of "extra" energy that the particles have. You've been told to find the increase in their mass due to relativistic effects.
What (very famous) equation link energy and mass?
