Answer
Find out the what is the acceleration of the object .
To prove
Formula
Where
t = the time in which the change occurs
As given
If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .
Final velocity = 98 m/s
Intial velocity = 65 m/s
Time = 12 s
Put in the formula
Acceleration = 2 .75 m/s ²
Option (A) is correct .
