The problem:
Here is the definition of rate of change of one quantity with respect to another:
The average rate of change of A with respect to B on an interval is
average rate of change of A with respect to B = (change in A) / (change in B)
Apply the above definition of average rate of change of A with respect to B to each of the following. Be sure to identify the quantity A, the quantity B and the requested average rate.
If the position of a ball rolling along a track changes from 10 cm to 20 cm while the clock time changes from 4 seconds to 9 seconds, what is the average rate of change of its position with respect to clock time during this interval?
answer/question/discussion:
Quantity A = 20cm - 10cm = 10cm
Quantity B = 9sec - 4 sec = 5sec
So the average rate of change of A with respect to B = 10cm/5sec = 2cm/sec.
If the velocity of a ball rolling along a track changes from 10 cm / second to 40 cm / second during an interval during which the clock time changes by 3 seconds, then what is the average rate of change of its velocity with respect to clock time during this interval?
answer/question/discussion:
Quantity A = 40cm/sec - 10cm/sec = 30cm/sec
Quantity B = 3sec
Average rate of change = (30cm/sec)/3sec = 10cm/sec^2
If the average rate at which position changes with respect to clock time is 5 cm / second, and if the clock time changes by 10 seconds, by how much does the position change?
answer/question/discussion:
Quantity A = X
Quantity B = 10sec
Average rate of change in position with respect to clock time = 5cm/sec
So 5cm/sec = x/10sec
50cm = X = Quantity A, so the position changes by 50cm.
You will be expected hereafter to know and apply, in a variety of contexts, the definition given in this question. You need to know this definition word for word. If you try to apply the definition without using all the words it is going to cost you time and it will very likely diminish your performance. Briefly explain how you will ensure that you remember this definition.
answer/question/discussion:
I wrote the definition down in my notes and plan to memorize this definition.
You are asked in this exercise to apply the definition, and given a general procedure for doing so. Briefly outline the procedure for applying this definition, and briefly explain how you will remember to apply this procedure.
answer/question/discussion:
1. Calculate the change in A.
2. Calculate the change in B.
3.Divide the change in A by the change in B.
I wrote this application outline in my notes and plan to memorize it.
