A 0.4 kg bouncy ball is dropped from a 11 meter buldingit bounces up to a height of 9.5 meters. How much energy was lost in the system?

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

found in the nucleus

has mass of one amu

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.
