Calculate the impulse applied to a 15. kg mass if a force of 20. N is applied to the object for 5.0 s. O 4.0 kgm/s O 100 kgm/s (2 sig figs) O 60. kgm/s O 6.7 kgm/sA circus performer falls from a tight rope, falling into the safety net below. Which of the following best explains why the performer was not injured? The net O increases the time during which the momentum is changing, thus reducing the average force on the performer. 0 reduces the impulse to the performer. 0 decreases the time during which the force acts on the performer, thus reducing the change in momentum. 0 provides the necessary force to stop the performer. Accelerating a 2.0 kg object from 4.0 m/s to 8.0m/s requires what magnitude of applied force, if the force is applied for 0.25s? 32 N 16 N 24 N O 8 N
