Since substances break down much faster under aerobic conditions, as oxygen helps break the molecules apart, in a process called oxidation, biodegradation that actually takes place does so slowly that effects may not be visible in decades after a product was buried, if even then.
Answer:
velocity of the car is 7.3516 m/s
Explanation:
M1v1a + m2v1b = m1v2a + m2v2b
775*30 + 1475*0 = 775*v2a+1475*11.9
Let v2a be x
23250 + 0 = 775x + 17552.5
775x = 23250-17552.5
775x = 5697.5
X = 7.3516 m/s
