1. Copy the files from Assignment 1 to Assignment 3.

2. Modify the PetFoodCompany header to mention a friend function called "computeBonusBudget". This method should compute the bonus budget as netIncome() * BonusBudgetRate and this method should exist in the driver program - not the Class defintion.

3. Modify the output of the program to display the results of the computeBonusBudget.

Enter Total Expenses: 600
Net Income = 400
Bonus Budget = 8

A 28.5 kg block is being pulled by a force F = 245 N up along a rough incline. The coefficient of kinetic friction between the block and the incline is μk = 0.30. The block is pulled through a distace of 21.0 m. Angle is 33 degrees.

(a) Solve for the magnitude of the normal force FN (in Newtons)? Calculate the work (in Joules) done by the normal force. Pay attention to the angle in the work formula and the sign of work.

(b) What is the magnitude of the kinetic frictional force (in Newtons)? Calculate the work (in Joules) done by the kinetic frictional force. Pay attention to the angle in the work formula and the sign of work.

(c) Calculate the work (in Joules) done by the pulling force F. Pay attention to the angle in the work formula and the sign of work.

(d) The block starts from rest at the bottom of the incline. After it is pulled through a distance of 21.0 m up along the incline, what is its vertical height (in meters), hf? What is its speed (in m/s) after being pulled through 21.0 m?

(e) Add up the works (in Joules) done by all NONCONSERVATIVE Forces:

Hypothesis: Anti-smoking television PSAs reduces cigarette smoking.

Study design: 500 Individuals were randomly assigned to watch a PSA about wearing seat belts (control group) and 532 individuals were randomly assigned to watch a PSA about the dangers of smoking (treatment group). A week after the study, the same individuals were asked to complete a survey. In the control group, 102 people reported smoking cigarettes in the previous week and in the treatment group, 85 people reported smoking cigarettes in the previous week. (15 points)
