There's a wagon standing on a hill(adsbygoogle = window.adsbygoogle || []).push({});

The Height :0,81m

When v1 = 0m/s then v2 = 4m/s when the wagon has rolled down the slope.

What is the velocity when the startvelocity is 2m/s ...

How do I do this...

I've tried many things but I don't know the mass so how should I do?

Please help
