#### Storyboard Text

• ﻿Last week when I was shooting at the range I discovered that the bullet was going 2600 ft./sec and it was 25 feet away from the gun. The second time it was 2600 ft./sec and the bullet was 250 feet away!
• I wonder how fast a bullet travels after you pull the trigger?﻿
• Exactly Jeff!﻿
• ﻿So that means I would have to calculate how fast the bullet was going each time you pulled the trigger? And from that information you gave me I would have to come up with an answer?
• That is correct!﻿
• ﻿﻿I'm not that good at math but im pretty sure the bullet goes -4 ft./sec each time the﻿ trigger is pulled. I think I'm almost done!
• If i plug in 300 I'm pretty sure I would get 3,900? and if I plug in 500 I would get 496?
• Now you have to find out how fast the bullet was going when it has traveled 300ft & how far the bullet has traveled when it slowed to 500 ft./sec﻿.
• Hmmmm, that would be 3,600? And when the bullet stops it will go -900 ft?
• ﻿Next step is to find out the speed of the bullet immediately after the trigger is pulled & when the bullet has stopped, calculate how far the bullet went.﻿
• ﻿Now I know why math is important! It helps you in real life problems, If i didn't know how to do linear equations and slope intercept form I would of never knew a bullet traveled -4 ft./sec!
• ﻿Jeff you got all the answers right!!
