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?
b.both speed and 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?
3)It takes 6 seconds for a stone dropped from rest to hit the botom of a well. What is its final speed?
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 :)
