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

a What is the initial velocity initial velocity?

Initial velocity=?

b) When does the object have a velocity of zero? If there Is more than one time, list all answers in a comma separated list.

$t=?$

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

A. This is how much the object has moved in 4 seconds.

B. This is the object's velocity in 4 hours

C. In this number of hours the velocity will be 4 t/sec.

D. This is the object's velocity in 4 seconds.

E. This is the average velocty of the object over the 4 second interval.

F. In this number of seconds the object will have moved 4 ft.

G. None of the above.
