Q(17,18,19,20) 2011 VCAA

[VCE_2012]

Can anybody think of anymore scenarios like this (where graphs of energy and momentum can be sketched from a collision or oscillations)?
I know that there is similar scenario in the 2010 exams, but what are other possible ones?

that question was also asked in 2008.. nearly exact same question.. look at tssm 2011 q12 for motion.. sick question.. but other than that the only other ones i can think of is as a asteroid moves away from a planet, lets say the moon, how will the kinetic energy differ from when it is closer/further away..
