What does it mean to put the most specific case first? Why is it important to put the most specific case first? What types of errors does it help avoid?

When writing an if-else-if statement you want to put the most specific cases first. In the temperature example above you want to check for temperatures over 100 degrees first. Afterwards the code checks for temperatures above 90 degrees, but because of the order the code is written you know that none of temperatures you'll find there are above 100 degrees. After all you would have caught them in the previous if-statement. This means you can be confident any temperatures you catch there will be between 90 and 100 degrees. As you continue through the if-else-if statement you use the same logic to check for different ranges of temperature.

Explanation:

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
