Matlab: Path Prediction Query

I'm doing a project on an autonomous tram and i need to able to predict the path of oncoming objects. However for the moment I'm only concerned with calculating this in a 2D graph, with x repesenting the distance from the scanner and y the angle.

A scan is taken at equal intervals, eg. every 1 second. Considering isolating just one object from the field and getting the object's general xy co-ordinate at each scan, after four scans I should have enough info to calculate the predicted path of that object, and represent its path as a curve.

What math is involved to calculate the velocity, acceleration, jerk, and predicted path for the object, using the x and y co-ordinates? Has anyone any experience in this?

This appears to be a straight forward physics question but I decided to post here as I using Matlab to programme. Does anyone know of any useful functions to aid me. Thanks.
