@JohnRennie Hi :-)

@Bml Hi :-)

Did you see the problem I sent?

Yes, but unfortunately I need to go soon.

Is there a diagram for the problem? It's not entirely clear to me where the mass and spring are.

@JohnRennie No, there isn't...

So the problem says we compress the spring to 0.2m i.e. we compress it by 0.3m.

OK so far?

Like that.

I need to go now. I will be here tomorrow morning as usual.

@JohnRennie Yes

Hi

Hi :-)

The initial energy of the system is 1/2 k ∆l^2, right?

The final energy is 1/2 m v_0² + 1/2 M V_0²

We will need to do this tomorrow. I have to leave in 40 minutes and I have a queue of questions stacked up. Sorry :-(

@JohnRennie Don't worry. Thanks. Let's see tomorrow...

Bye!

Bye
