Question

The table below gives the height of a rocket as a function time,h(t).

Units are in the table.

h (m)	0	66	164	295	457	651	878	1138	1429	1753	2108
t (s)	0	1	2	3	4	5	6	7	8	9	10

Air temperature is a function of height: T(h) = 300 − h/200

with T in kelvins and h as above. There is a temperature sensor on the rocket. How fast is the temperature, as measured by this sensor, changing at the instant when t = 6 seconds?

_______

Answer 1

dT/dh = -200 and is not a function of height
