CAPE Physics Unit 1 · 2004 · Paper 2 · Question 5(b)(i)

Two trolleys are used to investigate collisions. A trolley of mass 1.60 kg is pushed and hits a second trolley, of mass 0.80 kg, moving in the same direction but at a lower speed. The experiment is repeated and results are shown for 1st and 2nd collisions.

Show whether or not the two sets of data are consistent with the law of conservation of momentum.

The mark scheme is shown once you've answered.
