Kinematics Equation: Solving for t

AI Thread Summary
The equation v^2 - u^2 = kt^2/2m is questioned for its validity and application in kinematics. Participants note that it appears to combine elements from the standard kinematic equations x = x_0 + v_0 t + (1/2) a t^2 and v^2 = v_0^2 + 2 a Δx. Clarification is sought on when and how to use this equation correctly. The discussion highlights confusion regarding its derivation and practical use in solving for time (t). Understanding the proper context and formulation of kinematic equations is essential for accurate application in physics problems.

When we apply this equation ?
v^2-u^2=kt^2/2m

Not sure what that equation is supposed to be. It looks like a mash up of these two:

##x = x_0 + v_0 t + (1/2) a t^2##

##v^2 = v_0^2 + 2 a \Delta x##

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
