The policeman also watched a truck that was sitting at the red light. when the light turned green, the truck slowly started moving, getting faster and faster until it was going a constant velocity. what do you think the motion graphs looked like? explain why you think they look this way.

I think the motion graphs would slope higher and higher as the truck goes faster and faster until it stops again.

Explanation:

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.
