Q: 2 cars A and B race each other the car A ran for2 minutes at a speed of 7.5 km/h , then the car came to rest for 56 minutes and again ran for 2 minutes at the speed of 7.5 km/h. find the average speed of the car. please answer fast with explanation

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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.

ingenuity says that the answer is 2.7 m.
