Did you figure it out?

If we plug all our given values into the equation, we get this:

-16 = x(1/2) – 1/2(32)( 1/2)2

If we simplify that equation, we get this:

-16 = x(1/2) – 4

If we then solve for x, we get -24. The initial velocity of the computer is therefore 24 feet per second straight down.

 

 

 

 

 

 

 

 

 

 

 

Did you figure it out?

If the gas tank is 1/5 full, then it will need 4/5 × 15 = 12 gallons of gas to fill it. The 12 gallons of gas it takes to fill the tank costs $1.45 × 12 = $17.40.
