- 3. A person stands on a hill that is 78m tall. If their gravitational potential energy is 40,000J, what is the person’s mass? 4. What is the mass of an object that creates 33,750J of energy by traveling at 30m/s?How much work is done by 2 kg fish that changes its speed from 1 m/s to 3 m/sThe world record for ethanol fuel efficiency is 10705 miles per gallon [mi / gal] If the vehicle is given 400 grams [g] of ethanol (specific gravity = 0.789) and driven until the fuel ran outhow far did it go in kilometers [km
- The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?How much work is required to stop a 2000 kg car moving with a speed of 30 km/hr?5. What is the kinetic energy of a baseball whose mass is 0.15kg if it is thrown with a velocity of 22m/s?
- what is the kinetic energy of a 1500 pound car traveling at 40 meters per secondWhat is the kinetic energy of a 0.43-kg soccer ball kicked at 36.5 m/s?A person consumes 1500 kcal/day while expending 2500 kcal/day. In a month’s time, about how much weight would this person lose if the loss were essentially all from body fat? (Body fat has an energy content of about 4100 kcal per pound.)
