Question 10 0.66 pts Read the introduction to Tutorial 7 in the Tutorial Manual to help you answer the questions below. If there is no net external force on a system, it is possible that Afim does not equal zero for the system so long as Ay also does not equal zero for the system. 0 True 0 False Question 11 0.67 pts Consider a 5 kg object moves with a velocity of g = (6 m/s)i + (8 m/s)r . What is the magnitude of the momentum in kg m/s? 0 70 kg m/s 0 -70 kg m/s 0 50 kg m/s 0 -50 kg m/s 0 40 kg m/s 0 -40 kg m/s 0 10 kg m/s 0 -10 kg m/s 0 -30 kg m/s 0 30 kg m/s Question 12 0.67 pts Consider the object in the last question. What is the x-component of the object's momentum? O 70 kg m/s 0 -70 kg m/s 0 50 kg m/s 0 -50 kg m/s 0 40 kg m/s 0 -40 kg m/s 0 10 kg m/s 0 -10 kg m/s 0 30 kg m/s 0 -30 kg m/s
