vi = 0 m/s a = 3.9 m/s^2 d = 56m vf^2 = vi^2 +2a*d vf^2 = 0 + 2(3.9*56) vf^2 = 436.8 m/s vf = 20.8997 m/s =21 m/s This is the speed of the car after it has traveled 56m.

Another variable could be tax, which is also in money.. Ex: y = 0.15x + x Where 0.15 is the tax % and x is the price of the product. This will tell you have much more you will have to pay on the store value.

Well, one example could be Velocity in m/s, km/h, etc... You could use the equation: D=v/t and say that it's used in daily life to calculate... Speed, while also determining time and distance for engineering.

A carnival ferris wheel completes five turns about its horizontal axis every minute. What is the acceleration of a passenger at his/ her lowest point on the ride? I understand that 1/f= T which is how you find the period and that minutes must be converted to sec, but I'm ...

**algebra**

also, if you have a chart the x values in the chart represent the data range used for interpolation while anything lower than the min x value will be extrapolation and any term higher than the max x value will be extrapolation.

**algebra**

use interpolation when the data falls within the range given by the model (when it says "based on data from such and such to such and such" or "this data applies to years x to y" when the year or time you're studying falls outside this range then you ...

thanks for your help!! The radius was 15 m so ac was 4.11 m/s^2 if you were wondering :) thanks again!

An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at +40 ft/s2. After some time t1, the rocket engine is shut down and the sled moves with constant velocity v for a time t2. If the total distance traveled by the sled is 17 500 ft ...
