WTH??? LMAO.. ok, what is going on..

question 60 and 61 don't make any darned sense. the explanation in the back of the manual for these two quiz in lecture questions are rediculous and don't make any bit of sense... can someone explain this... Thanks

Are you talking about the lecture questions, or the 30 minute exam questions?

What exactly don't you understand? It might help to explain it if we know what you're having issues with.

actually I got them... now... It was a little tricky but I guess the explanation makes sense...

Furthermore the other one was like damned tricky too.. 61... these are the quiz questions...

choice D makes sense because you are introducing an initial velocity to the projectile. 25 m/s is the highest Vo out of the bunch.
