Link 0 Link 5 A horizontal Slinky is at rest on a table. A wave pulse is sent along the Slinky, causing the top of link 5 to move horizontally with the displacement shown in the graph. x (cm) 2 4 6 8 10 (a) Is this a transverse or a longitudinal wave? Explain. D, (cm) 0- 0.1 0.3 64 (s) 0.5 0.2 (b) What is the position of link 5 at /= 0.1 s? -11 What is the position of link 5 at / 0.2 s? , (cmk) What is the position of link 5 at 1= 0.3 s? Note: Position, not displacement. (8) 0.5 0- 0.1 02 0.3 0.4 Draw a velocity-versus-time graph of link 5. Add an appropriate scale to the vertical axis. (c) QUESTION 9 contd. (d) Can you determine, from the information given, whether the wave pulse is travelling to the right or to the left? If so, give the direction and explain how you found it. If not, why not? Can you determine from the information given, the speed of the wave? If so, give the speed and explain how you found it. If not, why not? (e)
