i'm having trouble following the math involved. Can someone set me straight?
Vf^2 = V_0^2 + 2aD
73.3^2 - 80^2 = 2aD
-1022.27 = 2(3-9.81sin(7)x_f
-511.1355 = (3-9.81(sin7))x_f
-511.1355 = (3-1.1955)x_f
-511.1355 = 1.8044*x_f
x_f = -283.26 feet.
What am i missing?
I got an answer, but it seems rather low. I think I saw somewhere that Velocity = flowrate/area*density
so I have 16/(pi*0.04 m^2)*(1000)
The units work out to be m/s and I got 0.127 m/s That's some slow moving water! Does this work?
Homework Statement
Water (of density 1000 kg/m^3) flows into a cylindrical tank through two pipes at mass flow rates of 6 kg/sec and 10 kg/sec respectively, and leaves the tank via a circular outlet pipe of 20 cm diameter. If the water level in the tank is to remain constant, calculate the...
alright, so I need to set up a kinematics. You have to avoid the variable t, so you can use the equation:
V_f^2 = v_i^2 + 2ad
The final velocity will be 0
0 = vi^2 + 2ad
vi^2/2a = d
Since we only care about velocity and displacement in the y direction, the equation changes to
d =...

2. The attempt at a solution
I have the solution, but it's pretty confusing so I want to see if anyone else can walk me through step by step. The first step is pretty clear...You have to find the acceleration that the proton will experience as it moves towards the...
Homework Statement
The figure below shows a Helmholtz coil used to generate uniform magnetic fields. Suppose the Helmholtz coil consists of two sets of coaxial wire loops with 17 turns of radius R = 76.6 cm, which are separated by R, and each coil carries a current of 0.131 A flowing in the...
