Final answer:
The calculation of velocity at different times requires information about initial velocity and constant acceleration. Without this information or specific context for a body's motion, the correct velocities cannot be determined simply based on the times provided.
Step-by-step explanation:
To find the velocity at various times given a constant acceleration, we can use the equation of motion v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
For instance, if a particle starts with an initial velocity of 2.0 m/s and has a constant acceleration of 6.0 m/s², its velocity at any time t can be found using the aforementioned equation. The velocity at 5 seconds would be calculated as v = 2.0 m/s + (6.0 m/s² * 5 s) which equals 32 m/s.
However, in the case where we don't have values for initial velocity or acceleration, and are simply given a list of times and asked to identify corresponding velocities from options (a) to (d), further information would be required to solve for velocity or we may need to match given velocities with times if we are analyzing the motion of a body.
In the examples provided in the question, it seems that the correct velocities are context-dependent and cannot be confirmed without additional information about the motion under consideration.
