In a car, the speedometer measures instantaneuos speed right? And the speed limit signs refer to instantaneous speed too? How long does it take light to travela distance of 1 km? When an object moves at constant velocity, does its average velocity differ from its instantaneous velocity?

I use a 600ft rope for work. I usually wrap it up to move it. I also happen to be very able to carry it. But when all the ropes hanging off the side of a building, it feels much more heavier to pull back up. Why is that?

What time is required to reduce velocity from 157km/hr to 75km/hr?
How long does it travel during that time?

I got 108.2 seconds, and 3.21KM...

Yet on a similar question of..
Car travels at 65km/hr, brakes decelerate at 6m/s^2. To stop, it'll take 3.009s and 27.16M til it stops moving.. I'd like verification on this and help with the one above:D

so i have an idea to make a hover boad heres my plan

get some newdinium (i know wrong spelling) magnets and place 5 that are capable of holdig 55lbs on a deck and 5 of the same drilled into the ground. they will be faceing so the polarities are not connectiong but are actually forcing each other away..... does this sound like a plan ? o should i not waste the money ? i have tried it on semi small scale with some regular magnets and the only probem seems to be balance. so any ideas to improve mine ? or do you think i should go along with it..... i think i will do it not matter what i just wanna hear some ideas thanks

A model airplane of mass 0.75 kg is flying at constant speed in a horizontal circle at one end of a 30 m cord and at a height of 18 m. The other end of the cord is teathered to the ground. The airplane circles 4.4 times per minute and has its wings horizontal so that the air is pushing vertically upward.


I don't need anyone to solve the question for me. How would I find the tension of the cord? I have already drawn a free-body diagram

What will be the total time elapsed until it reaches earth?
I also had to answer...
a)How high will it rise? I got 797.5M
b) How long until it reaches that height? I got 12.76s

For my 1st question, theoretically I could double "b". Anyone wanna verify?

Has this equation been made before?


Time is realated to distance,
If X. and Y, have different distances, X being long, Y, being short, to reach their destinations at the same time x must travel faster then then Y.
So if Yis a shorter distant then X,
Then X has to have faster movement to = the same amount of time that passes for Y.

Yreaches it destitation at a slower amount of speed. Yet at the same amount to time.

Short distance and long distance= same amount of time that passes.
Long distance must = more then speed then
short distance.
Lond ditance= Ld =x
Short distanace= Sd= Y
Speed=s
Same amount of time= sat
>greater then, < less then

x>s=sat =y
Example equation.
Distance X=7miles
Distance Y=4miles
Sat = 5mins
S=speed, varible.
7>s=5mins=4>s

Should I revise this some how?
