# Velocity Table

My question I don't understand how to add a colums for total distance.

Construct a table of values of velocity and total distance fallen at the end
of each half-second during the first 5 seconds for a stone at rest dropped
from a very tall building. Include columns for time, velocity, and total
distance

Time of Fall Velocity Aquired Distance
(seconds) (meters/seconds (meters/seconds
_______________________________________
0--------------------- 0---------------------0
0.5-------------------4.9--------------------1.225m/s
1--------------------- 9.8-------------------4.9m/s

2 ------------------- 19.6------------------19.6m/s
2.5------------------24.5--------------------30.625m/s

I know you know how to find the distance an object falls as a function of time. Use the basic kinematics equation for accelerated motion.

(You won't need to add columns.)

total = d=49m

Re: Re: Velocity Table

No. What you've done is give a table with columns for time and speed, not distance. I think you need a table with three columns: time, speed, and distance.

$$V=at$$

$$D=\frac{1}{2}at^2$$

I'm hoping someone can help me.

I'm working on this same Velocity table and need to understand a couple things. Is velocity the same as the speed... it should be should it? also, I'm looking for distance and while I have these equations I'm not sure what to do? Physics online is a little more difficult then I realized. But I feel if I get thru the initial reminders of calculus, I'll be just fine.

If someone could do an example even unrelated... it would be sooo helpful. thank you

Using the formulas V=aT & D=1/2aT2

....................................................V=aT...............D=1/2aT2
T2=Time....a or g = Speed m/s..... V=Velocity...........Distance
0......................0...............................0......................0
.5.....................4.9.............................2.45
1......................9.8.............................9.8
1.5...................14.7............................22.05
2......................19.6............................39.2
2.5...................24.5............................61.25
3......................29.4............................88.2
3.5...................34.3............................120.05
4......................39.2............................156.8
4.5...................44.1............................198.45
5......................49...............................245

Is this right so far?
