What should be left out of financial decisions whenever possible

Emotion

Explanation:

Everyone knows that when it comes to making financial decisions, emotions should be set aside and reason based. However, few can actually do this. To make the right financial decision, choose times where your emotions are under control.

Intense emotions, good or bad, keep us from acting clearly about money.

Note that when we are too happy we tend to be more optimistic, and consequently we act that everything will work out. Conversely, we may miss good financial opportunities by extending our negative emotions from other fields of life (bad relationships, for example) to financial decisions.

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
