Aferrari with an initial velocity of 10 m/s, comes to a complete stop in 5 seconds, what will its acceleration be?

Acceleration = (change in speed) / (time for the change)

Change in speed = (speed at the end) minus (speed at the beginning)

Change in speed = (zero) minus (10 m/s) = negative 10 m/s

Acceleration = (-10 m/s) / (5 sec)

Acceleration of the Ferrari = -2 m/s²

Democratically, it doesn't have to be a Ferrari. If my 16-yr-old Dodge is going 10 m/s and stops in 5 sec, its acceleration would be the same number.

it becomes positively charged by charging it
