When t = 0, the train has a speed of 8 m/s, which is increasing at 0.5

Question:

When t = 0, the train has a speed of 8 m/s, which is increasing at 0.5 m/s². Determine the magnitude of the acceleration of the engine when it reaches point A, at t = 20 s. Here the radius of curvature of the tracks is ρ_A = 400 m.
