Hi, in this question it is given that the roller coaster ride starts with a car at rest at point a.
00:07
At this point the car is starting from rest.
00:10
We need to rank the we need to rank from greatest to the least.
00:17
The speed.
00:19
That is the part a is the speed.
00:24
We need to rank the speed at each point.
00:28
Then after that in the part b we need to rank the kinetic energy.
00:33
Energy of the core at each point, then in the point c we need to rank the potential energy of the core at each point.
00:52
The speed of the core, let us start from the path a.
00:56
The speed of the car will be maximum at the lowest point on the curve and minimum at the highest point on the curve.
01:03
Therefore, from this we can find that the lowest point is the point d.
01:07
Therefore, we can rank the speed.
01:12
The speed will be greater at the point d.
01:15
After that, there will be slightly less at the point b...
