Homework Statement
1 question: How much work must be done to launch a 100-kg object to a height of 2 x 10^3 kilometer above the Earth's surface?
2.A person with the mass of 10 kg jumps up and down on her mattress with a spring constant of 4.3 nK.m. She does this by applying a sinusoidal...
Yes! This is exactly what I wanted. Thank you so much, this is starting to make sense.
Now, I have two final questions.
Will R = √[(A1+A2cos∅)^2 + (A2sin∅)^2] always be true or is it just when A2>A1? would R = √[(A1+A2cos∅)^2 + (A1sin∅)^2] if A2<A1. I don't think it would be, I just want to...
But yes, that is what I am wondering about. What if the amplitudes are different. Even though, I strayed from this in my last post. Take the example of the lines of y1=3cos(4x-1.6t) and y2= 4sin(5x-2t -.250), how would you go about finding the new amplitude of the combined waves at any...
Okay, I feel a little stupid and I was just frustrated! My question was more along these lines. What if they did not give us the x and t, but they gave us the phase shift as .25, so the question would be along the lines of y1=3cos(4x-1.6t) and y2= 4sin(5x-2t -.250) and we were asked to find the...
Homework Statement
The question asks us to find the superposition of 2 waves where y1=3cos(4x-1.6t) and y2= 4sin(5x-2t) and find the superposition of the waves y1 + Y2 at x=1 and t =0.5
