Final answer:
This question requires additional specific information in order to determine the acceleration of the slider blocks when the angle theta equals 105 degrees. The information provided includes several examples of relevant physics problems that could provide a conceptual basis for solving the question.
Step-by-step explanation:
In order to determine the magnitude of the acceleration of the slider blocks at the instant θ = 105 ∘, information about the forces acting on the block and its orientation would be necessary. From the context, we can only see examples of how to solve such problems, such as a stratagem for a reel to come to a stop, determining magnitude of vector components, and calculating acceleration in scenarios where friction is negligible or frictional force is present, among others.
For example, for the case of a 2.5-kg block sliding on a frictionless table, the actual acceleration would depend on factors like the elasticity of the spring it bounces against, or the initial velocity of the block. The equation a(t) = 5.0î + 2.0tĵ − 6.0t² km/s² is an example of how you might model the acceleration over time in such a scenario, given certain initial conditions and forces.
