Aspring is stretched 6 cm when mass of 200g is hung on it calculate the spring constant of this spring plz it's for my !

This question involves the concept of Hooke's Law.

The value of the spring constant is "32.7 N/m".

According to Hooke's Law, the change in length of a spring is directly proportional to the force applied to it. Mathematically,

where,

Therefore,

k = 32.7 N/m

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.
