2. Assume that the brakes in your car create a constant deceleration of 3.9 m/s2 regardless of how fast you are driving. If you double your driving speed from 15 m/s to 30 m/s, does the time required to come to a stop increase by a factor of two or a factor of four. Verify your answer by calculating the stopping times for both speeds?

radiation

explanation:

heat is transmitted by radiation

answer; how far out of place which the object finished relative to the starting location;

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.
