A person who has a weight of 158 pound-force [lb; on Earth is travelling to Mars in a spacecraft. As long as the engines on the spacecraft are not operating, the person is essentially weightless
during the voyage. During a course correction, the spacecraft undergoes an acceleration of 0.81 g. The tem "g" is the Earth-normal gravity, so 1 "g" is 9.8 meters per second squared [m's1. This
acceleration makes it feel like there is gravity in the spacecraft, and the person will have a perceived weight during the acceleration period, rather than feeling weightless.
Once the person reaches Mars, what is the mass, in units of kilograms [kg), and weight, in units of pound-force [lb], of the person on Mars? The gravity of Mars is 3.71 meters per second squared
[mis").

Henry Ford’s Model T was originally designed and built to run on ethanol. Today, ethanol (190-proof alcohol) can be produced with domestic stills for about $0.85 per gallon. When blended with gasoline costing $4.15 per gallon, a 20% ethanol and 80% gasoline mixture costs $3.28 per gallon. Assume fuel consumption at 25 mpg and engine performance in general are not adversely affected with this 20–80 blend (called E20).
How much money can be saved for 15,000 miles of driving per year?
1.What is the specific gravity of natural gasoline, if the data for 3 trials are the following:
hW = 7.8 cm, 6.5 cm, 9.5 cm and hL = 11 cm, 9.5 cm, 13.5 cm, respectively. (Tabulate the data and show solutions.)

You have decided to drive your old Ford out there, which gets approximately 18 miles to the gallon when cruising at 70 mph. Because Grandma is an excellent cook and you can stay and eat at her place as long as you want (for free), you want to get to Seattle as economically as possible. However, you are worried about your fuel consumption rate at high speeds. You also have to balance cost of food, snacks, and sleep to balance against the cost of fuel. What is the optimum average speed you should use so as to minimize your total trip cost, CT?arrow_forwardThe cost fuel in running a locomotive is proportional to the square of the speed and is P25 per hour for a speed of 25 miles per hour.
