Individual

• Ashrita Furman holds several world records. In 2004 he set the world record for the fastest 100m on a space hopper. He traveled at 3.31 m/s on the space hopper. How long did it take him?

Individual

• In 2010, he set the record for the fastest mile on a space hopper. It took him 13 minutes flat. What was his average velocity in m/s?
• 1 mile = 1609 m
• 1 minute = 60 seconds

Individual

• Ashrita also holds a world record for potato sack racing. In 2007, he raced at an average velocity of 1.607 m/s for 1001 seconds. What distance did he travel?

Fun fact: Ashrita holds the World Record for the most world records held by one person (currently 202)

Individual

• The current fastest airplane is the Lockheed SR-71 Blackbird. It set the record in 1976, with a velocity of 980.4 m/s. If the circumference of the Earth is about 40,000,000m, how long would it take the Blackbird to go around the world in hours?

Individual

• To get her world record, Joanne Singleton ran at an average rate of 3.67 m/s for 5745 s (1 hour, 35 min, 45s) dressed as a strawberry. How far did she run?

Individual

• Tom Wiberg built and rode the world’s smallest motorcycle. He traveled 10 m in 18 seconds. What was his average velocity?

Homework: Prepare for Success!
• Review the worksheets we did the last couple of days.
• Review this powerpoint
• The answers are posted after this slide
• Slide 2: linear, constant
• Slide 3: time, position, velocity, initial position
• Slide 4: negative direction because of negative slope, negative velocity because of negative slope
• Slide 5: B because it has a steeper slope, they have the same position at the same time (they meet, pass, collide, etc.)
• Slide 6: B because it has a steeper slope, No because they never have the same position at the same time (the lines do not intersect)
• Slide 7: 6m, 0m, -6m, 2m
• Slide 8: 30.21 sec
• Slide 9: 2.06 m/s
• Slide 10: 1608.607m (1 mile)
• Slide 12: 11.3 hours
• Slide 13: 21084.15 m (a half marathon)
• Slide 14: 0.556 m/s (1.24 mph)
