What is the answer to (d)?

If A and B have the same frequency and time period, that doesn’t necessarily mean they have the same speed, does it? (c) = 0.033 m/s btw.

>that doesn’t necessarily mean they have the same speed, does it?
meh, but close enough. also the amplitudes are of the same magnitude.

Who gives a fuck?

These guys get it.

Ok thanks - do you have any ideas how I'm supposed to justify using v = 0.033? I'll lose marks for not showing workings if I don't provide an explanation, I imagine. That's what my teacher is like :/
