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.
