Physics Review Question Unit: motion Year: 1996 Question#: 17 Question: A bullet traveling at 5.0 x 10^{2} meters per second is brought to rest by an impulse of 50. newton-seconds. What is the mass of the bullet? (1 ) 2.5 x 10^{4} kg (2 ) 1.0 x 10^{1} kg (3 ) 1.0 x 10^{-1} kg (4 ) 1.0 x 10^{-2} kg What is this question really asking? Explanation by: Joe W [ Return to question menu ] Answer 1 2.5 x 10^{4} kg INCORRECT Try the concept return to top Answer 2 1.0 x 10^{1} kg INCORRECT Try the concept return to top Answer 3 1.0 x 10^{-1} kg CORRECT using the formula,Try the concept , you get a mass of 0.1kg, or 1.0 x 10^-1 kg return to top Answer 4 1.0 x 10 ^{-2} kg INCORRECT Try the concept return to top What's this question really asking? What mass traveling at 5.0 x 10^{2} m/s would a 50 newton-second impulse stop? return to top |
