The nose of an ultralight plane is pointed due south, and its airspeed indicator shows 35 m/s. the plane is in a 10-m/s wind blowing toward the southwest relative to the earth. (a) in a vector addition diagram, show the relationship of up/e (the velocity of the plane relative to the earth) to the two given vectors. (b) let x be east and y be north, and find the components of up/e. (c) find the magni- tude and direction of up/e

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.
