I Got 0 for the value and squareroot 5 for velocity. Is it possible that curvature p value is 0 in last question?. I have used following formula: x’*y”-x”*y’ divided to (x’2+y’2)^3/2

Is it possible? Yes.

Did you use the right formula?
Did you substitute the right values and calculate the right derivatives?

If it's zero, then it's zero. Check your work and go with confidence.
