A popular topic in early space exploration was how to safely return modules back to the surface of the earth. Early designs contained materials that could only withstand impulses of up to 
before parts of the module became compromised. One such model of mass 500kg is approaching ocean waters and deploys its shoot, reducing its speed to 
. If the module decelerates to zero velocity in 0.9 seconds upon hitting the water, is the module structurally compromised?

and collides with a car of mass 800kg traveling west at 
. Assuming the collision is completely inellastic, what is velocity of the first car after the collision?
