a 1,200-kg car is moving at 25m/s collides with a 9000-kg moving at 20.0m/s. They are both moving in the same direction. What is the trucks final Velocity?
thanks brahs

Is this a static or elastic collision?
If it bounces off then 23.3m/s, so 23m/s
If they stick together then 20.6m/s, so 21m/s
**** i dunno.. its physics I if that helps ya
howd you do that>?
It's probably elastic.
So the first one.
It's easy, all you do is multiply the 1200kg by 25 m/s and add it to 9000kg times 20m/s then you divide the whole thing by 9000kg, the weight of the truck.
It's momentum: p=m*v
