Miss Atkins is on her first space walk. Her mass is 80.0 KG and she carries an empty oxygen tank with a mass of 10.0 KG. She throws the tank away from her self with the speed of 2.0 m/s. With what speed does she start to move off into space? Both the astronaut and the Tanger motionless before she throws the tank.

answer; equivalent to a one(1) horsepower motor;

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.
