Explain how you would determine how much error there is between a vector addition and the displacement of the actual trip taken. Why arent vectors true straigh-line paths in the real world?
Would you expect the vector addition to be larger or smaller than the actual. trip taken? Why?

if someone could answer and explain it would be great. Thanks in advance!

it may be wrong but i think its a

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.
