    P2 near where it was taking about the positives of fusion

    It was "In a star"

    The answer 'A star' was probably a little crappy 'joke' by the examiners.

    Positives of fusion; doesn't produce nuclear waste, releases more energy per kg of fuel.

    Can someone explain how you work out the maximum height and the grav potential energy of the rocket. The change in height wasn't given so how could you work it out

    The gravitational potential energy gained=kinetic energy lost so the GPE and Ek where just the same. To find the change in height you just had to rearrange the equation using the number you got for GPE
