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.

does anyone know or what?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

a skateboard rolling across the street - apex

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome
