Wouldn't a massive amount of astronomical techniques and observing technologies be based on Relativity? It seems like that was really what the theories were about. I see no way how we could measure distance among other astronomical properties without relativity.

Oh wow, I didn't think the motion equations worked like that. Though, I guess being a second degree polynomial should have been a huge tip off. Problem solved.

I don't agree. All that equation says is that in 3.24 seconds the ball travels up 10 ft from zero. What's happening is the ball is traveling up to a height y2 then down to 10ft. Were also in ft here so it's easier to use ft/s2 for the acceleration. Anyway my exam is in 5 minutes so, hopefully...

I'm going to be expected to do this with just a scientific calculator. I know there is a simple way to figure this out that is just flying right over my head.

People who major in this will very often end up in things like construction management. It's not really an engineering job but it pays well and the work is not incredibly hard. Although I'm sure the best of the best in this field do work on some interesting/large projects where they get to make...

A field goal kicker kicks the football so that it leaves the ground with velocity V that is 50 degrees above horizontal. The ball travels for 3.24s and hits the crossbar 10.00 ft above the ground. Neglect air resistance. Find the velocity after the kicker kicks the ball. Find the horizontal...
