If a cheetah runs at 25 m/s, how long will it take a cheetah to run a 100 m dash?

It will take it 4seconds.

Explanation:

The cheetah runs 25m for every 1s. So if you divide 100m by 25m the number of meters it runs in 1s, you will get 4s.

because growing process had stoped after 4-5 year

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.
