A space shuttle is launched from rest. It takes 8.00s to reach 163 km/h , and at the end of the first 1.00m its speed is 1630 km/h .
1. What is the average acceleration (in m/s^2 ) of the shuttle during the first 8.00 s?
2. What is the average acceleration (in m/s^2 ) of the shuttle between 8.00s and the end of the first 1.00m ?
3. Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the first 8.00 s?
4. Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 8.00s to 1.00m ?

163 k/h = 45.277 m/s = V1
1630 k/h = 452.77 m/s = V2

1) a1 = V1/t1 = 45.277/8.00 = 5.66 m/s²
2) a2 = (V2 - V1)/(60 - 8) = 7.836 m/s²
3) d1 = V1²/(2a1) = 181.1 meters
4) d2 = (V2² - V1²)/(2a2) = 12,950 meters
