Having difficulty with the followingCalculating this collision, as the standard equation does not apply, i don't think.(adsbygoogle = window.adsbygoogle || []).push({});

Question 1:

A 2000kg car travelling at 24 m/s EAST (x), collides with a 3600kg truck travelling at 10m/s SOUTH(y). What is there velocity immediately after impact.

Question 2:

An Earth Satellite travels in a circular orbit of radius 4 times the Earths radius. Calculate its acceleration in m/s^2

Question 3:

A satellite circles the Earth at an average altitude of 760km, with a period of 100 min. Calculate the mass of the Earth, if G = 6.67x10^-11 Nm^2/kg^2, and the radius of the Earth is 6.38x10^6m.

Can you advise me the correct equation to use and directions, i'm lost. Please and thank you.

Josh
