3
Step-by-step explanation:
Round to nearest 5 - 15
Divide 15 by 5 - 3
Answer:
0.0015 km².
Step-by-step explanation:
It is given that a map is drawn to a scale of 1 cm to 250 cm.
It is given that an airport has an area of 240 cm² on the map. So, its actual area is
![[\because 1\ km^2=10000000000\ cm^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%201%5C%20km%5E2%3D10000000000%5C%20cm%5E2%5D)
Therefore, the area of airport is 0.0015 km².
One equation that could be used would be t = 25-12
Well 57+59+61= 177 so the answer is 57
Answer:
Step-by-step explanation:
Key features
when t = 0
the initial height is 143/3 = 47⅔ ft
initial velocity is -310/3 = -103⅓ ft/s (downward)
initial acceleration is 2(64) = 128 ft/s² (upward)
I would not like to ride this roller coaster!
that's about four times the acceleration of gravity, and it only increases as the car gets to the bottom of the curve at t = 1 s
For part 3
I'm not sure what they mean by "not realistic"
while the initial acceleration is high. the acceleration at t = 1 is zero except that in 'reality' the car would have to be going through a curve to change direction from down to up. That would create very high centripetal acceleration and therefore centripetal forces.
