Let $v(t) = t^2 - 2 t$ be the velocity, in feet per second, of an object at time $t$, in seconds.

(a) What is the initial velocity?
initial velocity = (include units: help (units))

(b) When does the object have a velocity of zero? If there is more than time, list all answers in a comma separated list.
$t =$ seconds

(c) What is the meaning of the quantity $v(4)$ ? Select all that apply if more than one statement is correct.

A. The object's velocity in 4 seconds.
B. In how many hours will the velocity be 4 ft/sec.
C. The average velocity of the object over the 4 second interval.
D. How much the object has moved in 4 seconds.
E. In how seconds will the object have moved 4 ft.
F. The object's velocity in 4 hours.
G. None of the above
