Acceleration is the rate at which the velocity of an object changes with respect to time, or in other words, how much an object is speeding up or slowing down. The average acceleration of an object can be found using the formula shown above, where t is the time over which the acceleration is being measured, vf is the final velocity, and vi is the initial velocity. Which of the following represents t in terms of the other variables?
A.
B.
C. t = a(vf - vi)
D.
