Answer:
7560 Joules
Explanation:
= Mass of first car = 
= Mass of second car = 
= Initial Velocity of first car = 0.3 m/s
= Initial Velocity of second car = -0.12 m/s
v = Velocity of combined mass
As linear momentum of the system is conserved

Energy lost is

The Energy lost in the collision is 7560 Joules
Answer:
This is to optimize storage and transport.
Explanation:
It is like that, except most nails are steel or stainless steel, slowing to rusting process to about 5 years.
