Explanation:

Composting, composting is the process of organic materials. If you were t throw away an orange on the ground it would decompose as if it were a dying plant. This is because the material is organic and grew from a plant.

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j
