Speed: Mass and Space Shuttle Endeavor

 What is the speed of a rocket that travels 9000 meters in 12.12 seconds?
 What is the speed of a jet plane that travels 528 meters in 4 seconds?
 After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a speed of 96 m/s. After 17 seconds, how far has the chip landed?
 The space shuttle Endeavor is launched to altitude of 500 km above the surface of the earth. The shuttle travels at an average rate of 700 m/s. How long will it take for
Endeavor to reach its orbit?
 How long will your trip take (in hours) if you travel 350 km at an average speed of
80 km/hr?
 How many seconds will it take for a satellite to travel 450 km at a rate of 120 m/s?

1. d=vt (distance = velocity multiplied by time) d=9000 m t=12.12 sec. solving for v, v=d/t, v=742.57 m/sec. 2. d=vt d=528 m t=4 sec solving for v, v=d/t, v=132 m/sec. 3. d=vt v=96 m/sec. t=17 sec. d=1632 m 4. d=vt d=500,000 m v=700 m/sec. solving for t, t=d/v, t=714.3 sec.(11.9 min.) 5. d=vt d=350,000 m v=80,000 m/hr. solving for t, t=d/v t=4.375 hrs. 6. d=vt d=450,000 m v=120 m/sec solving for t, t=d/v, t=3750 sec.

Problem 1
An African elephant can reach heights of 13 feet and possess a mass of as much as 6000 kg. Determine the weight of an African elephant in Newtons and in pounds. (Given: 1.00 N = .225 pounds)
58800 N or 13230 lb
Problem 2
About twenty percent of the National Football League weighs more than 300 pounds. At this weight, their Body Mass Index (BMI) places them at Grade 2 obesity, which is one step below morbid obesity. Determine the mass of a 300 pound (1330 N) football player.
136 kg
Problem 3
With fuel
