What is the velocity of the two connected objects after the collision?

Answervery high orbital velocities in a very compact region;

Answermarble and quartzite

Answer a descending mass of air will have its temperature increase because of the pressure exerted on it, because its temperature increases it will also be able to hold more water and feel drier;

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:
