A driver followed a man with a surfboard strapped on top. The driver claims that the van stopped so quickly that the surfboard flew backward, hitting his car and causing damage. He wants the driver of the van to pay for damage to his vehicle and medical costs. You are the judge in the case. Use Newton's laws of motion to write a judgment in the case.

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.

not too sure thinking all accelerations are pointed down
