where
is the acceleration of the object in
,
is the net force on the object in Newtons, and
is the mass of the object in kilograms.
As a result,
.
Assume that all other forces on this object are balanced. The net force on the object will be . The net force is constant. Acceleration should also be constant and the same as the average acceleration in the two seconds.
