By observing the given graph The acceleration of the object would be -2.5 m/s², in other words, one can say the deacceleration of the object is 2.5 m/s²
What is acceleration?
The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².
acceleration =change in velocity/change in time
The slope of the velocity time diagram represents the acceleration of the moving object
As we can see from the graph the Y axis is representing the velocity and the X axis is representing the time
The Y coordinate changes from 40 m/s to 10 m/s and the X coordinates change from 0 s to 12 seconds
slope = (10 -40 )/(12-0)
acceleration = 30/12
acceleration = -2.5 m/s²
Thus, By looking at the provided graph In other terms, the object's acceleration would be -2.5 m/s2, or its deacceleration would be 2.5 m/s².
