10. Mr. D. is standing on top of the gym roof, holding a 6 kg bowling ball. He has calculated that if he drops the ball it will hit the ground with a speed of 14 m/s.
a. What kinetic energy will the ball have just as it hits the ground?
b. What potential energy does the ball have as Mr. D. holds it on the top of the roof?
c. How high above the ground is Mr. D. holding the ball?
11. Brady is sitting in his car in the lower lot uiti

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

im guessing the west of station 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.

the maxium height is 34m/s
