Suppose that another car is moving with a speed of 18.5 m/s when the brakes are applied so as to slow the car down at a rate of -2.85 m/s. a. What will be the speed of this car 3.55 seconds after the brakes are applied? (Round to 1 decimal)
m/s
b. How far will this car move during this 3.55 second period? (Round to 1 decimal)
meters
c. How long will it take for this car to stop? (Round to 1 decimal)
seconds
d. How far will this car move from the time that the brakes are applied until the car comes to a stop? (Round to 1 decimal)
meters

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.
