**Understanding Train Acceleration**An accelerograph records the acceleration of a train. Assume the train was moving in a straight line and the velocity of the train at \( t = 0 \) was \( 0 \, \text{m/s} \). Some of the data values for the acceleration of the train are shown below.**Table of Acceleration Values:**| Time (\( t \)) in seconds | 0 | 1 | 2 | 3 | 4 ||--------------------------|---|---|---|---|---|| Acceleration (\( a(t) \)) in \( \text{m/s}^2 \) | 3 | 2 | 1 | -1 | -2 |**Answer the questions using this information:**1. The table indicates that \( a(1) = 2 \, \text{m/s}^2 \). What does this tell you about the velocity?2. The table indicates that \( a(3) = -1 \, \text{m/s}^2 \). What does this tell you about the velocity?3. When is the velocity of the train going to be the greatest? Defend your conclusion by clearly explaining your reasoning or approach to solving this problem.

Given data: The velocity at t=0 is u=0. The relation between velocity and acceleration is, t(s)…
