Final answer:
Displacement requires time or distance during acceleration for calculation; the given velocities and acceleration alone are insufficient to find displacement without additional data.
Step-by-step explanation:
To calculate the displacement of an object with an initial velocity and a constant acceleration, one can use the kinematic equation:
s = ut + \(\frac{1}{2}\)at^2
where s is the displacement, u is the initial velocity, t is the time, and a is the acceleration. However, the question does not provide the time duration for the velocity change, so we cannot calculate the displacement directly. To solve this, we would need either the time taken to accelerate from 2 m/s to 5 m/s or the total distance covered during the acceleration. Without this additional information, it is impossible to determine the displacement.
