Do you mean in general or in a piece of paper?
I think it’s speed will increase, if I understood it correctly
Acceleration = (change in speed)/(time for the change)
Change in speed = (end speed) - (start speed)
Change in speed = (10 m/s) - (20 m/s) = -10 m/s
Time for the change = 5.00 seconds
Acceleration = (-10 m/s) / (5 sec)
<em>Acceleration = -2 m/s²</em>
That's choice-A .
The tendency of an object to resist a change in motion is called inertia.
