Is the magnitude of the change in momentum of object A in experiment 1 greater than, less than, or equal to that in experiment 2? Explain.
The change in magnitude of the object
Explanation of Solution
Introduction:
Momentum has both magnitude as well as direction because it is a vector quantity. It is calculated by using the product of mass and velocity of object during motion. The total system’s momentum is equal to the vector summation of the individual momentum.
The change in momentum is given by product of mass and the change in velocity.
For experiment
The change in momentum is given by:
Thus, the direction of motion is along the velocity direction.
Therefore,
The change in momentum vector for experiment
For experiment
Magnitude of velocity vectors from both resultant velocity vectors:
Therefore, The change in object ‘s momentum for experiment
Conclusion:
The change in object’s momentum for experiment

- Part A The two spheres A and B each have a mass of 400 g. The spheres are fixed to the horizontal rods as shown in (Figure 1) and their initial velocity is 2 m/s. The mass of the supporting frame is negligible and it is free to rotate. Neglect the size of the spheres. If a couple moment of M = 0.9 N m is applied to the frame, determine the speed of the spheres in 3 s. Express your answer to three significant figures and include the appropriate units.
