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

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.

1. you are correct

2. average speed = distance/time

3. speed = acceleration x time

so #2 is A and #3 is D?

Thanks so much :)

correct!!
