I for one do not believe a baseball can curve. it can arc, but thats all. and it can't rise either unless you throw it upward.

For our physics class we have to make a tennis ball launcher and we are also responsible for doing calculations to predict the distance our launcher will be able to launch the tennis ball.

I have done the calculations here and can be seen in this PDF file:
http://imusion.net/backup/yahoo.pdf

The diagram of our launcher can be seen in here:

I have looked through it but I know it is wrong. For u = 0.5kx^2 which is the first equation, x is the distance we can stretch the bungee cord which is supposed to be 1.2m and not 1.2-0.955(0.955 being the "slack " length of the cord). The problem is if I use 1.2m for x and follow through with everything else I get a ridiculous number like 500m. Which I know is not right.

Just a short explanation of what else I did for the calcs. After I found the PE of our bungee cord I found the velocity then used projectile motion.

If anyone can look through what I did and see what I did wrong I would appreciate that.

i hav the mass of an object which is 560,000 kg
i have the speed of the same object in m/s = 250 m/s
and i need to find the Pressure in Pascals
i know that Pressure = Force / Area
and Pressure = mass / length x time^2

is it correct if i do this-
Pressure = mass / length x time^2
Pressure = kg / ms^2
or Pressure = kg / [(ms^-1) x s^3]
therefore Pressure = 560,000 / 250 x (1^3)

i have assumed that since speed of object is 250 metres per second, s = 1 second, and therefore s^3 = 1^3 = 1
therefore Pressure = 560,000 / 250
= 2240 Pa or 2240 N/m^2 in other word 2240 kg/ms^2
is this correct?
i wud appreciate an explanation if it is or if it isn't

Are there any instruments that turn electromagnetic waves into images?

I know the question isn't really clear but I don't mean the television. Aren't televistion rays just translations of signals sent through waves. I mean waves directly converted into images like x-rays.

Let's say radio waves for example. What would a picture of a star look like in radio waves?

if we have 75, four-hundred pound men, sitting in a bus which is traveling at 168 miles per hour down the hi-way.... what is the average speed of this bus, if after 20 miles, these large men begin yodeling, pissing off the bus driver, thus slowing the bus to 98 miles per hour for 3 minutes...
during this time, the bus driver will tell these large yodelers to cease their yodeling... then the bus driver will increase the speed of the bus back to the original 168 miles per hour... so what is the average speed of this bus after 60 minutes???
