This is not a physics question. Just hoping for advice for any people who taken this course in high school. My school is a block schedule so I take AP physics B and AP physics C in one year. Currently, the first semester i am making 23% on tests and the highest was a 40%. I am one of the top...
Homework Statement
1. If v is constant, how does f change if λ quadruples?
2. c is equal to 3x10^8 m/s. What is the value of n if v equals 2.25 x 10^8 m/s
3. If n2 is greater than n1, is Ө1 greater than, less than, or equal to Ө2? Prove using third equation.
4. Assuming Ө2 is 90 degrees...
Homework Statement
Given v0= 0 m/s, xo=0 m and t= 10s, use the equation below together to find Xf
Homework Equations
x=xo+vot+(1/2)at^2
vf^2=vo^2+2a(xf-xi)
The Attempt at a Solution
vf=at xf-1/2at^2 vf=2axf
so then,
plug in t=10 and vf=10a
xf=50a ...
I don't know...
The equations used are:
1)ΣF=ma
2)fk = μkN
3)fs ≤ μsN
4)Fs = - kx
Here are the questions:
1. If ΣF is 10N and a=1 m/s^2, find m using the first equation
2. Given ΣF = fk, m=250 kg, μk=0.2, and N = 10m, find a.
3. ΣF=T-10m, but a=0 m/s^2. Use the first equation to find m in terms of T...
