1. Nascar driver, Jeff Gordon, has a car that is one of the fastest on the circuit. If it travels 600 miles in 4 hours, what is his cruising speed? 600miles 4 hours s= S= 150 miles/hour (mph)

2. The fastest car on Earth, a German-made Thrust SSC, would win every Nascar race in America. If it takes 0.5 hours (30 minutes) to travel 380 miles, what is its speed? 380 miles.5 hours s= S= 760 miles/hour (mph)

3. The fastest train on Earth, the TGV from France, can travel at faster speeds than trains in the United States. During a speed test, the train traveled 800 miles in 2.5 hours. What is its speed? 800miles 2.5 hours s= S= 320 miles/hour (mph)

4. Spirit of Australia, a hydroplane boat, made speed records by traveling 239 miles in 0.75 hours (45 minutes). What is its record- breaking speed? 239 miles.75 hours s= S= 318.66 miles/hour (mph)

5. The fastest plane ever made, the Lockhead SR71, was able to travel 11,000 miles in 5 hours. How fast can the plane go? 11,000miles 5 hours s= S= 2,200 miles/hour (mph)

6. Of all the machines on this worksheet, which one is the fastest?

SMASH LAB

1.How long have airbags been around? a.10 years b.25 years c.over 50 years 2.What is the normal purpose of airbags? a.to protect the vehicle b.to protect pedestrians c.to protect passengers inside a car 3.Every year, trains crush ____ vehicles a.50 b.1500 c.3000

4.Why did the team crash a train into a car at the beginning of the experiment? a.because it was fun b.to get a baseline reading c.they weren’t sure what would happen to the car 5.The team chose a train speed that can cause fatal injuries. What was the speed? a.25 mph b.50 mph c.75 mph 6.To test a train airbag, what two things did the team need to be able to do? a.move the car off tracks b.manually trigger the airbag c.both A and B

7.How fast does the gas go into the airbag when it inflates? a.50 mph b.200 mph c.500 mph 8.Why were each of these tested materials eliminated? (matching) _____ inner tubea. too rigid (stiff) _____ basketballb. tears too easily _____ inflatable boatc. not eliminated 9.How did the guys protect themselves from the exploding materials? a.wore safety goggles b.stood behind a plastic barrier c.did not use any special protection B A C

10.Why was each of these methods of moving the car eliminated? (matching) _____ wedgea. hit too hard; car stayed on tracks _____ flipperb. trolley (train) derailed _____ pivotc. not eliminated 11.How did the team do a full scale test on the pressure relief valves? a.jumped on an airbag b.dropped a car on a moon bounce c.guessed what would happen 12.Was the test successful? yes no 13.Did the team learn anything from the failed test? yes no B A C

Write a 2-3 sentence summary of the result of the final test using the real train and car.
