Question

A man is filling a pot with water, and it is not yet full. He turns a handle to increase or decrease the flow of water from the sink. Let V be the volume of water in the pot, measured in cm3, and t time measured in seconds. No water leaves the pot before it is full. Note: You do NOT need to explain your answers for this question.

1. (a) What are the units on dV / dt

2. (b) While the water is running but the man is not turning the handle, is dV/dt

positive, negative, or zero? Is d2V/dt^2 positive, negative, or zero?

(c) While the man is turning the handle to turn off the water, but the water is

still running, is dV/dt positive, negative, or zero? Is d2V/dt^2 positive, negative, or zero?
