I would say problem A is more like problem 1. Both deal with a stick and a glob of clay. We are looking for different values but I would say problem A is more like problem 1 than problem B

I would Solve Problem A most like the original problem only becasue problem A has to deal with rotational motion as does the original problem unlike Problem B.

A is most like the problem. They both deal with the force of static friction between the clay and stick. And both will require the formula a (towards center) = v^2 / R<BR>

I would say that problem A could be solved by the same method. This is because both of the objects are placed on friction-less surfaces and both objects have one end as the pivot and the other end free to move. Also, both objects also have an additional mass added to them through the experiment. Its just that in the inital question you are given the angular velocity after the addition of the additional mass and in A you are given the angular velocity prior to the additional mass.

Problem A.<BR>I think that solving problem A would be most like the original problem, since it includes many of the same ideas. With both it would be necessary to calculate the inertia, force, and angular velocity (one being the variable).

A.) letter A takes inot account some of the basic yet essential parts of the initial question. Both problems deal with a rotoation at one end on a FRICTIONLESS surface. The difference is that the position of the clay does not account for the ability to easily calculate force between the two, but the same principals of physics will be used in each problem.

A, the first problem calls on the same principles of physics as the first. I would be calculated the same way. You would just solve for the first position of the clay not after it moved.

The solving style would be most like the style used for problem A. It is not similar to problem B, because. The inclined plane portion of the problem has nothing to do with the above example. This partof the problemn gives the force that mass be generated by gravitational acceleration acting on the hanging mass. The mass is then determined with the equation F = ma. Problem A is similar to the above problem in that a stick is rotating through its center along with a clay mass attached. They are different in that problem A involves the law of conservation of momentum and the original problem does not.

I would solve problem A most like problem 1. The physics fundamentals are the same, and although the data is clearly different, and you're asked to solve for something else, the method of solving the problem doesn't change. Problem B might seem easier, and indeed it may be easier, to solve, but the physics fundamentals there are different. In problem B, you need to relate force with mass and acceleration. In both problem A and 1, you need to relate to the conservation of angular momentum, a very different principle.

I would solve problem 1 like I would problem A. Both have sticks spinning on a vertical axis and both have a lump of clay dropped on them. In problem 1 you are solving for the net force and in problem A you are solving for the final angular velocity of the class. I would start both problems by find the moment of inertia using I=1/2mv^2. I then would calculate the acceleration and find the Force by using the equation Tou=Iaccelaration. To find the angular velocity in question A I would find the change in distance over the change in time.
