Energy Savings. For these questions, assume 365 days in a year.
44. Suppose you have a clothes dryer that uses 4000 watts of power and you run it for an average of 1 hour each day. If you pay the utility company 14? per kilowatt-hour of electricity, what is the average daily cost to run your dryer? How much would you save in a year if you replace it with a more efficient model that uses only 2000 watts?

If the track descends d = 6 m for every full revolution, 0 = 2π rad, determine the magnitudes of the components of force which the track exerts on the car in the r, 0, and z directions. Neglect the size of the car. Bonus: Develop a MATLAB program to solve for this problem.arrow_forward
