Carnivores is the right level
Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity.
hope this helps!
Answer:

Explanation:
Please find the image for the question as attached file.
Solution -
Given -
First of all we will calculate the velocity at point C,
As per newton's third law of motion-

Substituting the given values in above equation, we get -

Now we will determine the radius of curvature for the curve shown in the attached image

Differentiating on both the sides, we get -
meter
Acceleration on curved path

Final acceleration
