Newton's Laws Worksheets Show all work on a separate sheet of paper. 15. 15. While dragging a crate a workman exerts a force of 628 N. Later, the mass of the crate is increased by a factor of 3.8. If the workman exerts the same force, how does the new acceleration compare to the old acceleration? 16. 16. A rocket accelerates in a space at a rate of "1 9." The rocket exerts a force of 12,482 N. Later in flight the rocket exerts 46,458 N. What is the rockets new acceleration? What is the rocket's new acceleration in "g's?" 17. 17. A race car exerts 19,454 N while the car travels at a constant speed of 201 mph, 91.36 m/s. What is the mass of the car? [18-31 Weight and Mass] 18. A locomotive's mass is 18181.81 kg. What is its weight? MAGINTRAINEE 19. A small car weighs 10168.25 N. What is its mass? 20. What is the weight of an infant whose mass is 1.76 kg? 21. An F-14's mass is 29,545 kg. What is its weight? 22. What is the mass of a runner whose weight is 648 N? 23. The surface gravity of the Sun is 274 m/s2. How many Earth g's is this? 24. The planet Mercury has 0.37 g's compared to the Earth. What is the acceleration on Mercury in m/s2? 25. A plane crashes with a de-acceleration of 185 m/s2. How many g's is this? 26. A baseball traveling 38 m/s is caught by the catcher. The catcher takes 0.1 seconds to stop the ball. What is the acceleration of the ball and how many gs is this? 27. A very fast car accelerates from a rest to 32 m/s, (71.68 mph), in 4.2 seconds. What is acceleration of the car and how many g's is this? 28. The Space Shuttle travels from launch to 529.2 m in 6.0 seconds. What is the acceleration of the shuttle and how many g's is this? 29. The space shuttle's mass, (with boosters) is 654,506 kg. The average force of the shuttles engines is 25,656,635.2N. What is the acceleration of the shuttle in m/s2 and g's? 30. How can the answers to #11 and #12 both be correct?
