 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 prices for...
