what help need you in? the aim is to investigate the law of conservation of momentum or something along those lines and for equations you can use momentum formula p=mv, m1v1+m2v2(before)=m1v1+m2v2(after), and newton's first law.

but i only have results for consevation of energy.

*facepalm*
you can make your answers up. you need time it takes to land after leaving ramp (about 0.33s) and distance it lands at
then you can work out velocity and you should know the mass of the marble and ball
with that, you can get momentum
