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.
