3. Figure 3 shows a wooden block of mass M into which a bullet is fired and subse- quently, embedded. The block is suspended by inextensible, massless cables of equal length / and the impact of the bullet causes it to swing through a maximum angle of . The initial speed of the bullet is v and it has a mass of m. a) State whether momentum and mechanical energy are conserved during the impact. 12 marks] b) Assuming that the bullet comes to a rest rapidly, how fast is the block moving immedi- ately after? Express your answer as a function of m, M and v. [4 marks C) Show how you would, quantitatively, deduce the speed of the bullet by measuring • experimentally.
