Science & Mathematics - 10 December 2007

I got a book, but i never really studied the constellations and its hard to tell. I am in the Bay Area (by SF) in CA. Any help would be greatly appreciated. Please leave the direction i should face and the best times to look if you can. I also seem to be missing all the comets? Any heads up on those???

and allowed to float just outside earth's atmostphere...10 or so miles away, how would it move relative to the earth?

Also if such an object were equipped with some sort of burn resistant rope or fiber that dangled down through the atmosphere and would the rope remain stationary as seen from the earth's surface?

Alright here is my problem, a 5.00 kg block is moving at 5.00 m/s along a horizontal frictionless surface toward an ideal spring that is attached to a wall. After the block collides with the spring, the spring is compressed a maximum distance of 0.68m. What is the speed of the block when the spring is compressed to only one-half of the maximum distance?

A rubber ball of mass 0.2 kg is released from an upstairs window of a building and strikes the ground at a velocity of 30 m/s. The ball bounces upward from the ground at a speed of 20 m/s. What is the impulse for the time the ball is in contact with the ground (in N s)?

Thank you!

earth rotates on its axis and goes around the sun in an orbit right? so we are on a ball spinning around and around and around.....




couldnt people just jump in the air while the earth is rotating below them and then some down because of gravity???
and then land in a different spot??????????
