Okay now I tried to solve for Momentum and Potental Energy, just to get to the equations that you are at.
Conservation of Momentum, no problem, came up to the same place that you are.
Conservation of Energy on the other hand...I don't understand.
Part 2: Conservation of Energy:
Okay...
Step 1: Just mass 1 sliding down the incline to the point
just before it hits.
&v_{1}=?$&
\Delta K_{E}+\Delta P_{E}=W_{NC}
(K_{E1}-K_{E0})+(P_{E1}-P_{E0})=0
(K_{E1}-P_{E0})=0
K_{E1}=P_{E0}
\frac{1}{2}m_{1}v_{1}^{2}=m_{1}gh
\frac{1}{2}v_{1}^{2}=gh
v_{1}=\sqrt{2gh}...
Well actually I solved for them both, but I was too lazy to write the other one up here.
But the problem I'm having is that both v_1 and v_2 are unknowns, and are within each other's equations when I solve for them.
So when I plugin one for the other I wind up with a situation where I...
I solved for the speed of the first block just before it hits the second block, and this came out to be:
the square root of 2gh,
Where h is the height of the incline.
I assigned this to a varible called V_1.
Next I tried to solve for the speed of the blocks after they collide,
using...
Say I was wondering if I could maybe get some help with this problem.
In a physics lab, a small cude slides down a frictionless incline as shown in the figure below, and elastically strikes a cude at the bottom that is only one-half its mass. If the incline is 30 cm high and the table is...
47.
A rock is dropped from a sea cliff and the sound of it striking the ocean is heard 3.4s later. If the speed of sound is 340 m/s, how high is the cliff?
Could somebody map this one out for me, it isn't making any sense.
