Would you use sum of the forces = tension - (mg) = 0?
Then I'd solve for tension and use the linear density found above to calculate the velocity.
I think.
Homework Statement
A string of mass .03 kg and length 2 m is fixed at one end, and driven with an oscillator at the other end. The oscillator induces traveling waves on the string of the form y=A sin (kx-ωt) which traveled down the string, hit the fixed end, and get reflected back as a wave...
Thank you for your help so far.
a.) Changing a to -9.8 gives a final y-position of 2.837 m.
b.) Using the eqn. yf = yi + vit + 1/2at2 makes more sense because it takes into account the non-zero starting position of 1 m.
Therefore, t = 1.174 s
question:
Do I have to multiply this answer by...
Homework Statement
Girl kicks ball straight up, makes contact with ball 1 m above ground, initial velocity = 3 m/s
a.) How high does the ball go?
b.) How long until it hits the ground?
c.) If she had given it an initial x-component of velocity of 2 m/s (same y-component), how far would the...
*Devise a code for the digits 0 to 9 whose Hamming distance is 2.*
My efforts to answer this problem are kind of hard to explain, but I'll try. First I wrote out the digits 0 to 9 in binary. Then I tried to find a number that was only 2 numbers different from each one (get 2 ones when XOR...
