Given the initial position of a particle is x(0)=2m at t(0)=0s. At t=2s, what are the particle's (a) position, (b) velocity and (c)acceleration?

There is hardly enough information. If I told you I as at home on Tuesday, then asked you where I would be later, you could hardly answer.

You have provided insufficient information to answer that question.

To find the position, velocity, and acceleration of the particle at t = 2s, we need additional information about the particle's motion. Specifically, we need information about the particle's displacement, velocity, and acceleration as functions of time.

If we have an equation that relates the particle's displacement, velocity, and acceleration as a function of time, we can use that equation to calculate the values at t = 2s. However, as the information provided is not sufficient, we cannot directly determine the position, velocity, and acceleration at t = 2s.

To determine the position, velocity, and acceleration, we generally need equations of motion or information about the forces acting on the particle. Without this additional information, we cannot provide specific values for the position, velocity, and acceleration at t = 2s.

If you have any other related information or equations, please provide them, and I can assist you further in calculating the position, velocity, and acceleration at t = 2s.
