When we calculate the horizontal velocity from our shooting trials..is that to be used as the resultant or x component when we are calculating to launch at an angle? I've asked a lot of people and everyone is doing something different. People argue that the velocity coming from the launcher is the same no matter an angle which would mean using it as the resultant.....but others say that it is the horizontal component because we specifically launched it at 0 degrees...anyone have a clear answer on this? -Sophia Rha
On the calendar it says that we should do the chapter 4 problem set but I thought we are on chapter 3. Was this intentional, meaning we should go ahead and do chapter 4, or was it a typo?
SOS how do we do the clown problem? I'm at a state where I feel like I need to know some kind of advanced trigonometry relationship in order to figure out the launch velocity of clown B and the angle.
Thanks for heads up

ReplyDeleteThanks for posting this is exactly why I have a Blog! Will discuss in class.

ReplyDeleteWill the sets be graded individually or all at the end? I am also confused about it being chapter 4, and not chapter 3.

ReplyDeletecan you explain how to it works to find the radii of the planets in #24 of the ch4 problem sets?

I found 2 equations. (1) is r=sqrt(GM/a) and (2) is r=[d*sin(alpha)]/[1-sin(alpha)]
