I think I've figured it out. I can solve for I, input that into
P=I2RL
Since I am trying to max. power dissipated by RL i can take the first derivative and set it equal to zero.
does this sound incorrect to anyone?
Homework Statement
One Thevenin theorem result is that the maximum power across the load resistor in the equivalent circuit (and therefore the real circuit) occurs when RL = Rth. Start with the result that the power dissipated by the load resistor is I2RL and prove this result.

okay, so i see that for the 2kg block and the 4kg block there is a 3rd law pair. (F of 4 acting on 2) so this will become an internal force
also there is the force from 6kg to 4kg and a force from the 4kg on the 6kg. this is also a 3rd law pair. so i will make it an internal force...
i now...
Homework Statement
Blocks with masses of 2kg , 4kg , and 6kg are lined up in a row on a frictionless table. All three are pushed forward by a 60 force applied to the 2 block.
how much force does the 4kg block exert on the 6kg block?
how much force does the 4kg block exert on the 2kg...
now this logically makes sense to me. d=v*t.
but since we have a constant acceleration (0) i should get the same answer using kinematics. now, solving for the x direction...
x= xo + Vox(Δt) + 1/2 ax (Δt)2
in this case xo and ax go to 0, so for the sake of ease, i will drop them from my...
well I've now found my time using the quadratic formula. this is a step i had not envisioned doing so for starters, thank you for pointing me in this direction.
now I've found my time, to be 5.45 seconds. this is the time it will take for the ball to travel straight up, and straight down...
my Yo would be the height of the wall.
i will re calculate this to be sure, and then i guess use that value to determine the time it takes for the ball to travel up, hit its apex, and then reach the base of the wall, all in the y direction...
if i take that time, can i use it with my...
Homework Statement
A knight fires a cannon ball from the top of the castle wall. the cannonball is fired at a speed of 55 m/s and an angle of 27 degrees above horizontal. A cannon ball is accidentally dropped and hits the moat below in 1.4s.
how far from the wall does the cannon ball hit...
