A 0.40-km wide river has a uniform flow speed of 7.1 m/s toward the east. It takes 39 s for a boat to cross the river to a point directly north of its departure point on the south bank. In what direction must the boat be pointed in order to accomplish this?

plzz...help me solving this!!

Me and a friend talked about time travel and we asked each other if it is possible to travel through time.. Of course it may not be done now, but what about in the future.. He said, "maybe if we can travel faster than the speed light, we could"...
But how can a person travel faster than the speed of light? is this even possible? If yes, what are the basic things that can be used from the present time to be modified into a time machine...

In your answer, please include:
-your thoughts on time travel
-is it possible?
-how?
-what materials from the present time can we use to be modified?
-other information...

If traveling at the speed of light means time stops 4 you does that mean that traveling twice the speed of light make you travel backwards in time?

In 1905, an asker posed this question: "Can matter be transformed into energy?"

One answer said, "No, because both matter and energy are conserved, as basic principles of physics."

Some other guy, named Einstein, wrote a long essay on something called "relativity", containing a formula "e = mc^2", which he says allows matter to be transformed into energy.

No best answer was picked, so it went into voting. After several days, which answer do you think was chosen as best, and why?

I know that Einstein doesn't think so; but, with the new theories of membrane theory, string theory, etc., is there serious consideration among the scientific community as to whether one day this technology could be implemented?

I washed-up a glass tumbler in warm water and put it on the draining board. About 30 seconds later, it exploded into fragments with a bang. My TV was on, but the volume was quiet and I don't recall any music playing.

Another stone is thrown vertically down 1.00s after the first is dropped. The stones strike the water at the same time.
a) what si the initial speed of the second stone?
b) plot velocity versus time on a graph for each stone, taking zero time as the instant the first stone is released. You can just e-mail this to me .

Please don't just give answers but show me how becuse I really want to learn how to do it.

Thanks
