Let us consider the following figure

<em>figure</em><em> </em><em>is</em><em> </em><em>in</em><em> </em><em>pict</em><em>ure</em>

So, his/her total displacement = 2 blocks.

total time = 1 hour

Average Velocity

= Total displacement/ total time

= 2 blocks/ 1 hour

= 2 blocks/ h

So, her/his average velocity is 2 blocks per hour.

A body is oscillating up and down at the end of a spring. Let’s consider when the body is at the top of its up-and-down motion.
Klio2033 [76]

The velocity of the body is zero; option A

<h3>What is the motion of an oscillating body?</h3>

The motion of an oscillating body is known as simple harmonic motion.

Simple harmonic motion involves a periodical motion of a body whose acceleration is directed towards a fixed point.

For a body that is oscillating up and down at the end of a spring, considering when the body is at the top of its up-and-down motion, the velocity of the body at the top and down is zero since the body comes to rest at the top and down position of its motion.

In conclusion, oscillating bodies undergo simple harmonic motion.
