What is the displacement of an object that moves from the origin to a position at -12 m

d = -12 m

Explanation:

Displacement is defined as change in the position of the object

it is the shortest distance between initial and final position of the object

so it is given as

now we have

so we have

so the displacement would be -12 m

it is 12 m in magnitude with negative direction displacement

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.
