### October Sky Discussion Questions:

1. Why are satellites visible only about an hour after
sunset and before dawn?

2. At the rate of an orbit every 96 minutes, how many
orbits could Sputnik make per day?

3. Why was Sputnik important? How have satellites and
rocketry changed life on Earth?

4. Use the formula to compute the height of a rocket
climbing 12 seconds and 14 seconds:

S = ½ at^{2}

S = distance (height) traveled

a = the gravitational constant = 32 feet per second
squared = 32 ^{ft}/_{sec}^{2} =
9.8 meters per second squared = 9.8 ^{m}/_{s}^{2
}t = time in seconds
