Answer to Question 1

We hope that they will make such a change. To be sure, the initial investment is
high, and some families might be too poor to afford the cost, even though they would
recoup the cost very rapidly. Look for some logic in the students' explanations.

Answer to Question 2

If the force exerted on the mass is twice as large and the mass is also twice as
large, the acceleration (the rate of change in velocity) is the same in both cases.
