Physics Review Question Unit: Mechanics Year: 1989 Question#: 12 Question: A force of 50. newtons causes an object to accelerate at 10. meters per second squared. What is the mass of the object? (1 ) 500 kg (2 ) 60. kg (3 ) 5.0 kg (4 ) 0.20 kg What is this question really asking? Explanation by: Yui H. [ Return to question menu ] Answer 1 500 kg incorrect This answer is incorrect because mass = Force / acceleration. 50.N / 10. m/s2 does not equal 500 kg. return to top Answer 2 60. kg incorrect This answer is incorrect because mass = Force / acceleration. 50.N / 10. m/s2 does not equal 60. kg. return to top Answer 3 5.0 kg correct This answer is correct because mass = Force / acceleration. 50.N / 10. m/s2 equals 5.0 kg. return to top Answer 4 0.20 kg. incorrect This answer is incorrect because mass = Force / acceleration. 50.N / 10. m/s2 does not equal 0.20 kg. return to top What's this question really asking? This question is asking you if you know the formula for calculating mass and be able to use that to calculate the mass of an object given a force and acceleration. return to top |
