Look both ways then cross the street
It is the posted speed.
Whatever the posted speed limit is.

False.
This is not related to physics but to the driver's attention when approaching a curve. If the speed is kept the same, it's more difficult to control the vehicle specially if the driver is stressed, drunk, tired or sleepy. The probability of an accident would increase on this situation.
AnswerIis legal to cross a solid line on the highway (or anywhere for that matter) unless there is a sign posted that states otherwise.Different countries have different rules regarding the rules of the road. You need to check the legislation in your area.

55 on the highway, and 30 in the city.
No faster than the posted legal limit!!
true
no
Naturally, I think you should slow down when you exit a highway but how much you should slow down ultimately is up to the driver. If you're not a very experienced driver then I would suggest that you slow down to the suggested ramp speed, which is posted before the ramp by a sign that has black letters and numbers with a yellow background. Those are suggested speed signs, those signs tell you a speed that you can safely take the ramp at. As far as exiting in general, yes you should.
