The equation v = a*del_t is sometimes used
to find velocity when acceleration and
time are known. Another form of this
equation is v = v_0 + a*del_t. In this second
form of the equation, the function of the
term v_0 is to:

 
A. indicate that the equation is valid
only for an object that starts at rest.
B. determine the time at which
velocity is equal to zero.

C. allow the equation to be used even
when an object has a nonzero initial
velocity.

D. allow the equation to be used even
when acceleration is not due to
gravity.
