The position versus time for a certain object
moving along the x-axis is shown. the object’s
initial position is 1 m.

find the instantaneous velocity at 1 s.
answer in units of m/s.

and explain !

Explanation:

The given graph shows the position versus time for a certain object  moving along the x-axis. We need to find the instantaneous velocity at 1 s. We know that the slope of position time graph gives the velocity and for a particular instant known as instantaneous velocity. Mathematically,

Taking slope of the given graph as :

At 1 s the position of the object is, and

So, the instantaneous velocity at 1 s is 3 m/s. Hence, this is the required solution.
