60,000 meters per hour
Step-by-step explanation:
Answer:
1.7 seconds
Step-by-step explanation:
we have
![H=-16t^2+vt+s](https://tex.z-dn.net/?f=H%3D-16t%5E2%2Bvt%2Bs)
where
v is the initial velocity (in feet per second)
s represents the initial height (in feet)
In this problem we have
---> because the object is dropped
![s=45\ ft](https://tex.z-dn.net/?f=s%3D45%5C%20ft)
substitute
![H=-16t^2+45](https://tex.z-dn.net/?f=H%3D-16t%5E2%2B45)
Remember that
When the chestnut hit the ground the value of H is equal to zero
so
For H=0
![-16t^2+45=0](https://tex.z-dn.net/?f=-16t%5E2%2B45%3D0)
solve for t
![16t^2=45\\t^2=2.8125\\t=\pm1.7\ sec](https://tex.z-dn.net/?f=16t%5E2%3D45%5C%5Ct%5E2%3D2.8125%5C%5Ct%3D%5Cpm1.7%5C%20sec)
therefore
The solution is t=1.7 sec
Answer:
30
Step-by-step explanation:
Ratios always remain proportionate. In this case, the simplified ratio has 1 red car. The question tells us that there are 6 cars. 6 is 6 times bigger than 1; thus showing that the ratio has increased by a factor of 6. If one side of the ratio increases by a factor of 6, then the other side must also increase by a factor of 6. Since 5*6=30, there must be 30 employees that own a black car.
