Q1. A 8.9 dog takes a nap in a canoe and wakes up to find the canoe has drifted out onto the lake but now is stationary. He walks along the length of the canoe at 0.54, relative to the water, and the canoe simultaneously moves in the opposite direction at 0.13 .

Q2. Adjacent antinodes of standing waves on a string are 15.0 cm apart. A particle at an antinodes oscillates in simple harmonic motion with amplitude 0.850 cm and period 0.0750 s. The string lies along the x axis and is fixed at x = 0.

a) How far apart are the adjacent nodes?

b) What is the wavelength of the two travelling waves that form this pattern?

c) What is the amplitude of the two travelling waves that form this pattern?

d) What is the speed of the two travelling waves that form this pattern?

e) Find the maximum and minimum transverse speeds of a point at antinodes.

f) What is the shortest distance along the string between a node and antinodes?

What is the wavelength of the two travelling waves that form this pattern?
