3 B.

i would choose the second problem becuase it deals with a mass that is not at the midpiont of the object. Eventhough the first problem sounds very close to the example, the lump of clay is at the midpiont which would have a different effect on the stick then if it was at one of the ends. Problem two is significent because the net force would need to be known to make sure the block does not move when released.

I would solve problem B more like problem 1. The force in problem 1 is the force that allows the clay to remain on the stick motionless. To solve this problem you would use the fact that the velocity of the clay with relation to the stick is zero. To solve problem B you would also be dealing with the velocity being zero. In this case the velocity of the block would have to be zero.

I would solve problem B most like problem 1. This is so, because net force is involved in both problems. In problem B, to find the value of the hanging mass, one would have to figure out forces acting on the block. And in problem 1, we are also looking for the net force.

B. Problem A is primarily focused on momentum conservation. Problem 1, however, is a problem where velocity is held constant and a force is desired. Likewise, problem B is also using a constant velocity and finding a force (in this case gravity). Thus B is solved most like problem 1.

B. because it deals with finding Force like question #1 (rather than velocity like A.).

B. In problem one we are trying to find a force like in B. In problem A we are trying to find a velocity.

I would solve problem B most like number 1. Both of the problems involve Torque, or force. Also, they both involve added masses and the effect that they have on the force applied. they just both seem very similar to me.

I would use problem B. Problem A gives the initial angular velocity of the system and wants you to find the final angular velocity after the lump of clay is dropped. This is much different then finding the force b/t the stick and the clay of the system problem. Instead it is more similar to finding the hanging mass value when the block does not move b/c in both you would have to deal with net forces.

I would solve problem B like problem 1. Both of these problems are force related problems using newtons second law. Problem A deals with angular velocity and momentum, which has nothing to do with the forces between the clay and the stick. In problem 1, the gravitational force and normal force will not be equal, due to the centripital acceleration. In problem B, the gravitational force and normal forces are not equal do to the force of tension involved and the incline. In each of these problems, you must first understand the relationship between the forces, and then you can go on to answer questions involving masses within the system and net forces.

I think I would solve problem B like the previous example because it deals with Torque which is analogous to Force=ma that you would use to solve problem B. Problem A deals witht the angular velocity which could be involved in calculating the acceleration to figure out the force, but in this case the problem only asks for velocity regardless of the force or torque. The tension, which is used to calculate the force, for the previos problem and problem B can be considered equal between the two systems. Whereas in problem A, the velocity is independent of the force.

Problem B is most like problem 1. This is true because solving for the net force between the stick and the clay, is like solving for the tension in the string of the masses.

B. Because in problem #1, and in problem B, the apparatus is already set up. In answer A, the clay is being dropped, so there would be initial and final values to take into account, requiring one to use the conservation of momentum or a similar equation. In #1 and in B, a similar approach would be used in which the force either of tension in B, or of total force in #1 would be calculated using F=ma or Torque=Ialpha, respectively.
