A ball is dropped off a ridge. At the same time, two more balls are kicked horizontally off the ridge. The third ball has a greater horizontal speed than the second ball. Because each ball travels the same distance in the vertical direction, accelerates with the same free-fall acceleration, and has an initial velocity of 0 in the vertical direction, each ball reaches the ground at the same time, t. a. Indicate how far each ball travels in the horizontal direction

what type of charge does it have? negative

real, smaller and upside-down.   so the answer should be b.

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.
