CAPE Physics Unit 1 · 2010 · Paper 2 · Question 1(a)(iv)

A ball of mass 0.60 kg is released from rest at the top of an inclined plane. A block is fixed at the bottom. The velocity (v) of the ball down the plane is measured at various times (t). Table 1 provides the velocity-time data.

State, with a reason, whether the collision between the block and the ball is elastic or not.

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