1.a block accelerates at 3.1 m/s2 down a plane inclined at an angle 24.0◦. find μk between the block and the in- clined plane. the acceleration of gravity is 9.81 m/s2 . 2.a 1200 kg car moves along a horizontal road at speed v0 = 20.1 m/s. the road is wet, so the static friction coefficient between the tires and the road is only μs = 0.189 and the kinetic friction coefficient is even lower, μk = 0.1323. the acceleration of gravity is 9.8 m/s2 . what is the shortest possible stopping dis- tance for the car under such conditions? use g = 9.8 m/s2 and neglect the reaction time of the driver. answer in units of m. you for the !

it doesn't. it was imagined up in the middle ages.

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.
