How is acceleration calculated?
a. initial velocity - final velocity / time
c. final velocity - initial velocity / time
b. initial velocity final velocity / time
d. final velocity / time

Explanation:

Let u is the initial speed of an object and v is the final speed of the object. t is the time taken to reach final speed v. Acceleration of an object is defined as the rate of change of velocity. Mathematically, it is given by :

or

So, the correct option is (c) .
