A sports car accelerates from 0 to 25 meters per second in 4 seconds. What is its acceleration? Question 1 options:

10ms2

6.25 ms2

25ms

0ms

20pts

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

its a 5.5 n

glad that

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.
