What is the method to estimate the acceleration of an object at a given time?

Calculate the area under the curve.

Determine the gradient of the tangent to the curve at that point.

Find the average speed over a set time

Find the total time of journey.

The gradient of the tangent to the curve at that point is used to calculate acceleration at a specific moment.
