29. What is the average velocity of an object that moves from 6.5 cm to 3.7 cm relative to the origin in 2.3 s?

Average Velocity = - 1.22 cm/s = - 0.0122 m/s

Explanation:

The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:

Average Velocity = Total Distance Covered/Total Time Taken

Average Velocity = (Final Position - Initial Position)/Total Time Taken

Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)

Average Velocity = (- 2.8 cm)/(2.3 s)

Average Velocity = - 1.22 cm/s = - 0.0122 m/s

here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.

attach the statements so i can 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.
