Hi. I haven't done physics for over a year and a half now, but my friend is taking the class. He asked for my help, but I really didn't know how to help him. Here are the questions...
1) Show how Delta y = (1/2)* (tan theta) * delta x
and why Delta y= (1/2) * delta y prime
2) Show why delta x is maximized for a given velocity when theta is equal to 45 degrees.
This is two dimensional motion. Here is the diagram:
Delta y Prime
| /\
| / \
| / \
| / \

|/ \
|-------------------------------
Delta X
The projectile motion is a line going from the beginning of the triangle, to the center of it, to the end of it. Delta Y is in the middle of Delta y prime and the middle of the triangle.
Sorry for the crude diagram. Please help!
