• 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?
The quantity A is the difference of position in cm and quantity B is the change in clock time. The change would be 20cm-10cm/9s-4s = 10cm/5s = 2 cm/s. The average rate of change is 2 cm/s.
• 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?
The objects velocity is changing by 30cm/s over a time of 3 s. The average acceleration is 30 cm/s / 3s = 10 cm/s^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?
The object is changing 5 cm/s and the clock time changes 10 s, so the objects position changes 50cm in 10 s.
• 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.
I will visualize the definition and write it down to help commit it to memory.
