Answer:

30[gal] would be requiered.

Explanation:

The consumption ratio is given by the following expression:

\frac{3.6[MJ]}{[1pass-km]}

To find the amount of energy needed we must multiply the ratio by the number of passengers, in this way the unit passenger-kilometer is removed from the denominator.

\frac{3.6[MJ]}{[1 pass-km]}*1[pass-1000km]\\\\ = 3600[MJ]

1 gal = 120 [MJ]

  x    = 3600[MJ]

x = 30 [gal]

Linear momentum has to be conserved. It was zero before the thread eas burned ... when nothing was moving ... so the momentum of the masses moving in opposite directions has to add up to zero. ... Momentum = mass times speed. ... In one direction, you have 5 kg times 1/5 m/s= 1 kg-m/s. ... We need 1 kg-m/s in the other direction. ... 7 kg times speed = 1 kg-m/s. ... Can you finish it from here ?
