In point a, they are asking what point on the car did you use to represent the car? now as we are going to draw a point model, it means we have to represent the car as a point mass.
00:20
Now, we know that every object can be treated as a point mass with respect to its center of mass.
00:29
So we will use the center of mass of car to show the car on the point mass model.
00:44
Now in part b, how we are going to show the car.
00:50
Now let this is the road.
00:54
Let this is the road and the stop signal is somewhere here.
01:02
Now as the car is approaching towards a stop signal, it means it's it's a speed.
01:08
Speed is decreasing.
01:10
So if now we know that the distance is equal to velocity into time...
