- that transfers ercray through matter or space. 3. Contrast how you would move a spring to make a transverse wave with how you would move a spring to make a longitudinal wave. 4. Give an example of a mechanical wave that is also a longitudinal wave. 5. Are seismic waves (waves throughout the Earth's crust)mechanical waves? How about sound? Light (electromagnetic waves)? In each case , if the wave is a mechanical wave, identify the medium. 6. Describe how the world would be different if all waves were mechanical waves. 7. The average speed of sound in water is 1500m/s How long would it take a sound wave to travel electromagnetic wave (light) travel in Conversions: ugght is 3times 10^6m/s.14aof for val units whole bunity voler in molars),Tris distance 18 hooras a li
- 4. If a rolling cart moves with uniform motion at a rate of 2m/s in the forward direction,what will its displacement be after 5 s? A. 0.4 m B. 2.0 m C. 10 m D. 100 m
- Section 4: Kinetic Energy and Speed 1: Write down the formula for kinetic energy. 2: If a car has a mass of 1,500 kg and is traveling at 20m/s calculate its kinetic energy. 3: Explain why speed matters more than mass in determining the damage in a car crash. Section 5: Crumple Zones and Safety 1. What is a crumple zone, and why is it important in car safety? 2: How does increasing the crumple zone length affect the force experienced during a crash?
