Question

Please help.
Sir Marvin decided to improve the destructive power of his cannon by increasing the size of his cannonballs. Sir Seymour kept his cannonballs the same size, but improved his powder to provide more velocity.
a.) Which knight will have the more destructive cannon? Why?
b) Jupiter is a more massive planet than either Saturn or Earth. Saturn is more massive than Earth. On which planet would an astronaut weigh the most?

Answer 1

why is b a completly diffrent subject?

Answer 2

I have no idea. this is how it is written on my science paper. The chapter is all about energy.
I think the answer is this but I really don't no.
a. Sir Seymore because doubling the mass doubles the kinetic energy, but doubling speed increases kinetic energy four times.
b. Jupiter, This is because more massive objects have a stronger pull than less massive objects. The mass of an object depends on it's size and composition.
