Working on it now - thank you!

That makes a lot more sense now. Thank you! I’m going to forget the calculation - I think it’s just confusing matters!

Thank you for bearing with me, but I’m still a little lost! If the velocity is 20 m/s isn’t the calculation still wrong? 10 - (-1 x 20) = 30 Emmy’s value for x at t = -1 is -10. So it still doesn’t seem to work.

The book says that Emmy is stationary and Nero is moving. So wouldn’t that make his speed relative to Emmy 10 m/s, if he is indeed moving at 10 m/s?

The quote from the book (in my original post) gives his speed as 10 m/s. The x coordinates only change by 10m at each second interval, so surely it has to be 10 m/s?

There are a couple of diagrams (hopefully attached) but they involve more frames of reference. The diagrams also introduce a child riding a bike and another dog. What’s confusing me is that the maths doesn’t seem to add up. From the explanation, it seems he’s saying that if you take the...

Hi everyone. Please be gentle with me, I am not a physicist! I am a layperson with an interest in learning more, and I’m reading a book called ‘How to Teach Relativity to Your Dog’ by Chad Orzel. It’s supposed to be physics for dummies, but it’s clearly not dumbed down enough for me because...
