Momentum Questions

Q5. The simplified diagram shows an experimental arrangement to investigate the collision of two trolleys.

In the experiment, trolley A is travelling at speed ν. It collides with and sticks to, the initially stationary trolley B.

(a) State the measurements you would need to take so that you could determine the speed of

(i) trolley A before the collision,

(ii) trolleys A and B after the collision.

(3 marks)

(b) Explain how you would verify that momentum was conserved in this collision, indicating what other measurements would be required.

(2 marks)

(c) State and explain what you would do to minimise the effects of friction on the motion of the trolleys.
