Attempting to stop on a slippery road, a car moving at 75 km/h skids across the road at a 30 degrees angle to its initial motion, coming to a stop in 3.9s .Determine the average acceleration in m/s^2 (meter per second square), using a coordinate system with the x axis in the direction of the car's original motion and the y axis toward the side of the road to which the car skids.

Solution:
1.) The car’s acceleration is opposite to the direction of the skid, since it comes to a stop,
So, for final velocity, Magnitude of acceleration,
In relation to the coordinate system...
