CAPE Physics Unit 1 · 2013 · Paper 2 · Question 4(b)(ii)c)

Two objects, of masses m₁ and m₂, travelling in opposite directions collide. Their velocities before collision (u₁ and u₂) and after (v₁ and v₂) are given in Table 3.

Was this an elastic collision? Explain why or why not.

This question uses a figure or table from the paper — you'll see it when you practise.
