  1. Converting and comparingunits Simple & Compound

  2. Which is larger? • 16 miles or25 km • 6 kg or12.2 pounds • 4 gallons or19 litres • 400 mm or 15 inches • 5 foot, 10 inches • or 1.65 m 41.6 km Convert the following: • 26 miles into km • 10 gallons into litres • 45 cm into inches • 2 litres into pints • 11 pounds into kg 45 litres 18 inches 3.5 pints 5 kg

  3. Near the start of his freefall, Felix Baumgartner’s speed was measured to be: 423 mph In km/h, this would be: 676.8 km/h In m/s, this would be: 188 m/s

  4. A common way of referring to supersonic speed is by Mach number, where: What was Felix’s maximum Mach number? Will it change if you use different units for speed? Over the course of his freefall, his maximum speed was measured to be: 843.6 mph If the speed of sound is: 300 m/s Did Felix break the sound barrier? Yes!

  5. How do we calculate average speed?

  6. Felix’s jump can be split into two stages: Freefall & Parachute He jumped from a height of 38969 m He opened his parachute at a height of 2567 mafter 4 mins 17 seconds. He was in air for a total of 9 mins 3 seconds What is the average speed for each of the two stages of his fall? How long would he have taken to fall, if he had fallen with the mean of these speeds?What do you notice?
