Final answer:
To determine how far the squirrel is from its initial position at t=5.40 s, the position function is required, which is unfortunately not provided in the question. In a similar problem with known acceleration and initial conditions, one could find the particle's position after a certain time using kinematic equations.
Step-by-step explanation:
The student's question pertains to the position of a squirrel running in the park at a specific time. However, the position function is not provided in the question. Based on the additional context, we could infer that the squirrel's motion might be described by a position-time graph or involves some kinematics concept such as velocity and acceleration. To find out how far the squirrel is from its initial position at t=5.40 s, we would need the position function, which typically has the form x(t) = x₀ + v₀t + (1/2)at². Without that information, it's impossible to give a precise answer. If we reference the similar example given, where a particle moves with an initial velocity of 0 m/s and a constant acceleration of 30 m/s², the particle's position after 5 seconds would be given by x = (1/2)at² or x = (1/2)*30*(5)² = 375 m from the initial position.
