Let's solve a given question.
00:02
In this question, a sled is traveling down, is traveling down.
00:13
Somewhere is a sled which is traveling down making a parabolic curve, making a parabolic curve having the equation that is y is equal to 0 .01 x square.
00:29
Here this distance is x which is equal to 60 meter.
00:33
From the top it is 36 meter.
00:38
We have to calculate the magnitude of the acceleration as the velocity v of a changes from 15 meter per second as it increases to v a dash which is equal to increases by the 3 meter per second.
00:56
So as a radius of curvature is given as that is radius of curvature of the curve of the pearl is given as r is equal to 1 plus dy by dx whole square to the power 3 by 2 divided by d square by y dx square.
01:36
On solving this as y is equal to 0 .01 x square.
01:43
So differentiating dy by dx with respect to x we get 2 into 0 .01 x that is 0 .02 x and the d square by differentiation of y with respect to x is given by that is 0 .02 meter per second square.

Here is the meter per second...
