What is the average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s

The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 .

Explanation:

Velocity is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. Then, the average velocity relates the change in position to the time taken to effect that change.

Velocity considers the direction in which an object moves, so it is considered a vector magnitude.

In this case, the displacement is 192 m and the time period is 8 s. Replacing:

Solving:

velocity= 24

The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 .

the answer is 3.1 his answer is wrong mines is right

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.
