Y= 1/2x-2
sybtract x from left to right
divide both side by -2
Answer:
y = 1609 ft
Step-by-step explanation:
g is equal to 9,8 m/s² or 32,18 ft/s²
According to g = 32,18 ft/s²
In the first second as y = -1/2 g*t²
y = 1/2 32,18*(1)² ⇒ y = 16,9 ft we dismiss the sign we know the object is falling down. Is enough for the purpose of this question
The second one
y = 1/2* (32,18)* (2)²
y = 32,18*2 ⇒ y = 64,36 ft
third second
y = 1/2*32,18*(3)² ⇒ y = 144,81 ft
And in the tenth second
y =( 1/2)* 32,18 * (10)² ⇒ y = 1609 ft
I believe SI is the international system of measurements, our metric system. You would want to use this when numbers begin to get too small, or too large. Some examples would be when calculating distances of spacial bodies such as the distance from earth to the center of the milky way which is about <span>1,000,000,000,000,000,000 km or 1*10^18. 1*10^18 is easier to write and is less confusing.</span>
