Physics - October 2006

A descent vehicle landing on Mars has a vertical velocity toward the surface of Mars of 5.5m/s. At the same time, it has a horizontal velocity of 3.5m/s.

Please help me.
I don't understand how to figure this problem out.

Here is the figure of the ring and the forces acting on it.
How would you find the net force acting on the ring?
I need help.

Currently, I'm taking a biology but I need to take two more science courses before I start my major courses. Plus, I maybe transferring to another institution soon and I need a certain amount of science courses before I leave. Should I do the following

1. Take two semesters of chemistry
2. Take two semesters of physics
3. Take one chem then one physics

**** In addition, if I take Chemistry, should I take the Introductory course first? If not, how should I prepare for such a class. Is there an introductory course to physics???

Traveling at a speed of 15.2 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.670. What is the speed of the automobile after 1.60 s have elapsed? Ignore the effects of air resistance.

hi every1
i have a little question here, when a pice of paper is put on a half full glass of water and the glass is flipped, the paper doesn't fall, why??
well i know if the glass if full, the paper doesn't fall because the pressure of water acting on the paper is less than that of air, but when it's half full three pressures act on the paper, two from inside the glass (air and water), and air from outside the glass, which -i think- makes the pressure of air and water inside the glass more than the pressure of air outside the glass..

can u give me a detailed explination plz..
thanks..

people often wonder if its possible to one day time travel (as in Dr Who),well i reckon if we could ever do that we would know by now simply because anyone who achieves this in the future would have come back in time and told us by now!!!!!!!!!!!!!!!!!!!!!

It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady , and the rope pulls up on the sled at a 26.0 angle. You estimate that the mass of the sled, with your friend on it, is 64.0 and that you're pulling with a force of 76.0 .
