If the impact force to ensure an elastic collision is 1700 N, how much air drag force is needed to apply to each of the prototypes to decrease the net force to at least 1700 N? (Hint: Use Net Force)

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.

technology is the application of the knowledge gained by science.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
