The time t, in seconds, taken by an object dropped from a height of s meters to reach the ground is given by the formula t = square root(s/5). Determine the rate of change in time with respect to height when the object is 125m above the ground.

The rate of change in time with respect to height when the object is 125m above the ground is 0.02m/s

Rate of change

Given the function that models the height reached by the object expressed as:

[tex]t =\sqrt{\dfrac{s}{5} }[/tex]

The rate of change of the function is expressed as:

[tex]\frac{dt}{ds} = \frac{1}{5} \times \frac{1}{2}*(\frac{s}{5})^{-1/2}[/tex]

Given that s = 125m

Substituting into the function

[tex]\frac{dt}{ds} = \frac{1}{5} \times \frac{1}{2}*(\frac{125}{5})^{-1/2}\\\frac{dt}{ds} = \frac{1}{5} \times \frac{1}{2}*(25)^{-1/2}\\\frac{dt}{ds} = \frac{1}{5} \times \frac{1}{2} \times \frac{1}{5} \\\frac{dt}{ds} = \frac{1}{50}[/tex]

Hence the rate of change in time with respect to height when the object is 125m above the ground is 0.02m/s
