When t =0, the train has a speed of 8 m/s. which is increasing at 0.5 m/s^2. Determine the magnitude of the acceleration of the engine when it reaches point a

When t = 0, the train has a speed of 8 m/s, which is increasing at 0.5 m/s^2. 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 treks is 400 m

= 0.9519 m/s²

≅ 0.95 m/s²

Explanation:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
