2) A woman carries a large bucket of water to the top of a 40 meter tower at a constant upward speed. The bucket has a mass of 10 kg and initially contains 30 kg of water, but it leaks at a constant rate and only 10 kg of water are in the bucket at the top of the tower. a) Write an expression for the mass of the bucket plus water as a function of the height y climbed. b) Find the work done by the woman on the bucket.

mistakes are ok

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
