Atruck has a minimum speed of 14 mph in high gear. when traveling x mph, the truck burns diesel fuel at the rate of 0.0065413(1024x+x)gal/mile assuming that the truck can not be driven over 56 mph and that diesel fuel costs $1.69 a gallon, find the following. (a) the steady speed that will minimize the cost of the fuel for a 580 mile trip. x= 31366.4 (b) the steady speed that will minimize the total cost of a 580 mile trip if the driver is paid $18 an hour. x= (c) the steady speed that will minimize the total cost of a 360 mile trip if the driver is paid $28 an hour.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

c) up

hope this

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
