Applying Laws of Projectile Motion to 45 Degree Angle

[puni12]

in a projectile motion, what law could be applicable to this sitaution?
if u want an example, umm let's say..
ur measuring porjectile motion for 45 degrees.,,
hat law or theory could be applicable to this?

 

[Doc Al]

The usual suspects: Newton's 2nd law and gravity.

All projectile motion is essentially the same: The vertical motion is accelerated downward; the horizontal motion is constant speed.

isnt it that to solve somehting like this needs a problem (according to the scientific method) and to make the problem, we have to base it on the objectives?
then what would be the objectives on this problem?
>to measure how far the 45 degree angle would be?
thanks

The laws regarding projectile motion are well known. Of course, to solve any problem you first need to know what the problem is. Do you have a specific problem in mind?

As Doc Al asked you need a specific problem. If your talking about projectile motion a few things come to mind. The angle(can be 45 degrees), acceleration, velocity, position...

umm.. i was planning to measure the projectile motion ith differnet angles..
so my problem would be um..
which angle will launch the farthest distance
is that enough?

What angle will maximize a projectiles horizontal distance? I think that would be a bit more exact.

thank you so much all!
