Me neither, exactly my question

And I see an error in my statement. The coefficient of integral of Fx is (2-m)/2, not m/2

Thanks hilbert. None of those are known. If you take a look at my work you see that what we are being asked is to simplify this integral from a long function of t (as you and I both indicate, it's basic physics to write x as a function of t) into a succinct statement. The point is not to...

Someone please help (; 67 views and no replies! It's lonely

Parabolic projectile Athena - you indicate you threw a ball at a parabolic path. I recommend you draw a parabolic path on your paper from left to right. The starting angle theta θ, is not zero since you indicate the ball arcs. How can you find θ? Once you solve for initial vx and vy, you...

Can you clarify the experiment? It is called Projectile but you indicate the ball only moved horizontally? In order to complete the problem correctly, one needs to know if this was a ball sliding on the ground or a parabolic path in the air

Homework Statement for particle with lagrangian L = m/2 dx/dt^2 + fx where x is constant force, what is ScL (classical action) Homework Equations d/dt (∂L/∂(dx/dt)) = ∂L/∂x ScL = ∫m/2 dx/dt^2 + fx dt from ti to tf The Attempt at a Solution d/dt (∂L/∂(dx/dt)) = ∂L/∂x implies f =...
