Harley Quinn is riding her motorbike south along a flat , horizontal road . The total weight of Harley and her hog is 1800 N. The engine exerts a 600 N force forward . The air resistance acting on Harley and the bike is 200 N. The total friction between the tires and the road is 100 N. a ) Draw a f. b. diagram for the system that includes Hayley and her motorbike.
b ) Calculate the net force on the system.
c ) Determine the mass of Hayley & her motorbike.​

i'm on my way to history not a mistory.

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.
