A. Mass and Weight 1. Find the weight of a 60 kg astronaut on earth a. Find the weight of the same object on a planet where the gravitational attraction has been reduced to 1/10 of the earth's pull. 2. A backpack weighs 8.2 newtons and has a mass of 5 kg on the moon. What is the strength of gravity on the moon? (Be careful with units, remember 1N= 1 kg * m/s_ 3. A physical science test book has a mass of 2.2 kg a. What is the weight on the Earth? b. What is the weight on Mars (g = 3.7 m/s) c. If the textbook weights 19.6 newtons on Venus, What is the strength of gravity on Venus? 4. Of all the planets in our solar system, Jupiter has the greatest gravitational strength. a. If a 0.5 kg pair of running shoes would weigh 11.55 newtons on Jupiter, what is the strength of gravity there? b. If he same pair of shoes weighs 0.3 newtons on Pluto, what is the strength of gravity on Pluto? c. What does the pair of shoes weigh on earth? B. Second Law of Motion 1. An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force? 2. An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force? 3. An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force? 4. An object accelerates 3.0 m/s2 when a force of 6.0 newtons is applied to it. What is the mass of the object? 5. An object accelerates 12.0 m/s2 when a force of 6.0 newtons is applied to it. What is the mass of the object? 6. An object accelerates 5.0 m/s2 when a force of 20.0 newtons is applied to it. What is the mass of the object? 7. An object with a mass of 20.0 kg has a force of 5.0 newtons applied to it. What is the resulting acceleration of the object? 8. An object with a mass of 3.0 kg has a force of 9.0 newtons applied to it. What is the resulting acceleration of the object? 9. An object with a mass of 2300 g has a force of 6.2 newtons applied to it. What is the resulting acceleration of the object?_ 10. An object with a mass of 3.2 kg has a force of 7.3 newtons applied to it. What is the resulting acceleration of the object?
