    Here are some muliple choice questions I am stuck on. Thanks in advance for help any one can give me.

    1) A falling object that has reached its terminal speed continues to gain?
    a.speed
    b.both speed and acceleration
    c.acceleration
    d.neither speed nor acceleration.
    I think the answer is D because once and object reaches terminal speed nothing changes...

    2)A car travels 30 meters in 5 seconds. What is its average speed?
    a.6 m/s
    b.25 m/s
    c.35 m/s
    d.150 m/s
    I think the answer in B

    3)It takes 6 seconds for a stone dropped from rest to hit the botom of a well. What is its final speed?
    a.6 meters/second
    b.30 meters/second
    c.36 meters/second
    d.60 meters/second.
    I think the answer is D.
