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 = at2

S = distance (height) traveled
a = the gravitational constant = 32 feet per second squared = 32 ft/sec2 = 9.8 meters per second squared = 9.8 m/s2
t = time in seconds
