Arace car completes the final lap of a race on a 2-kilometer circular track. at the start of the lap, it crosses the line at 60 meters/second. it completes the lap 28.57 seconds later, crossing the line at 85 meters/second. calculate the displacement and average acceleration of the car along the track over the course of the final lap. a. displacement is 0 meters, and acceleration is 0.88 meters/second2. b. displacement is 2,000 meters, and acceleration is 1.14 meters/second2. c. displacement is 0 meters, and acceleration is 70.0 meters/second2. d. displacement is 2,000 meters, and acceleration is 80.0 meters/second2. e. displacement is 0 meters, and acceleration is 0.70 meters/second2.

Displacement is 0 meters, and acceleration is 0.70 meters/second2.

hope this helped you

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.
