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.

a.) If an object is already moving and you applied another force parallel to it and with the same direction, does this mean that another counter force will be generated? Explain.
b.) Considering question (a), what if you applied a force lower than the force of momentum (and gravity, etc.) on the object, will it generate a counter force? Explain.
c.) On our activity, pushing the object at rest generates a counter force. How is this?

Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector r, but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive.
