This is the question: A rocket is fired vertically upward with an initial velocity of 80 m/s. It accelerates upward at 4 m/s^2 until it reaches an altitude of 1000m. At that point, its engines fail and the rocket goes into free flight, with acceleration -9.80 m/s^2. Now this is what I want to know: Will 1000m be the maximum altitude the rocket reaches since the engines stop at that moment, or will the rocket continue on? I know that at the maximum altitude, the velocity has to be 0 m/s, but according to my calculations using the data given, I get the final velocity of 120 m/s at 1000m. Please help!

Some people believe that poverty, hunger and overpopulation in developing countries are to be blamed for the serious environmental degradation. However, others argue that the serious environmental problems are the consequences of the high levels of consumption per person in developed countries.

As we sweep around the sun, are we moving in a straight line as a single object, or, since the Earth and Moon are the closest in size of any 2 planet system, are we like a couple of ballroom dancers moving as one unit around a central locus as we sweep across the dance floor? I hope I used locus correctly.

Under new guidelines for the indentification of planets there will now be 12 recognised planets instead of the current 9. With the new system, if a planitary body has enough gravity to pull itself into a sperical shape then it is a planet. The new proposal, which will soon be voted upon by a worldwide body of astronomers, puts planets into three groups:

The Classical Planets(8): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The plutons (small icy planets on the outer fringers of the solar system, of which there are currently 3, but this number may rise as new planets are discovered and identified, at the moment there are around a dozen other planets under investigation): The twin planets of Pluto & Charon (formerly Pluto's moon) and 2003 UB313 (now the furthest planet from the sun, it is bigger than pluto)

Ceres: Under the new system this former asteroid between Mars and Jupiter is now a planet.

It's not about the shape of the headphones, it's about the sound. It seems (and i may be wrong here) that even if it's a song I haven't heard, it just sounds a bit odd if i'm listening to the left speaker from theright and visa versa
