Select the correct answer. Galileo was the first scientist to do which of the following?
A. estimate the speed of light
B. propose the heliocentric theory
C. discover radioactivity
D. define and measure speed
E. invent the reflecting telescope​

he kicked it 10 feet straight up into the air? i think this works.

d is the correct answer

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.
