i got this question
did you got q4 & 5
only number 5 wich is (5/2)*R
the half loop one question and the spring block with friction one?
My bad.
I don´t know the other one
Half loop N= (k*d^2/m-2*g*R)*(m/R)
ocw.mit.edu/courses/physics/8-01t-physics-i-fall-2004/assignments/ps07sol.pdf
check q4 plug in your values, i got different values
i am figuring out the 2nd part
did you got vertical spring one?
did you get the 1st one.. plzz help anyone? plz
does anybody knows the last one(8th question) plzz. hop.
8th
a)(-C_1*r*v_x)/m
b)g-(C_1*r*v_y)/m
c)u*e^(-(C_1*r*t)/m)
d)((m*g)/(C_1*r))-((m*g)/(C_1*r))*e^(-(C_1*r*t)/m)
e)4.6*(m/(C_1*r))
f)0
g)(m*g)/(C_1*r)
did anyone got the vertical spring one?
q:1
@mk did you got the spring block question?
kunoi ,, vertical one please.!! tried many times plzz help!
question 3rd not getting b,c and d
plzz help
We release an oil drop of radius r in air. The density of the oil is 720 kg/m3. C1 and C2 for 1 atmosphere air at 20∘ C are 3.40 × 10−4 (kg/m)/sec and 0.93 kg/m3, respectively.
How small should the oil drop be so that the drag force is dominated by the linear term in the speed (in lectures we called this Regime I). In this regime, the terminal velocity is mg/C1r. [m is the mass of the drop].
r<<x
find x ??
anyone?
r << 1.3e-4
julia, the grader is not accepting the answer
1.66*10^-4
yeah i got it,, forgot to take the cube root.
the 8th one plz
not getting the 3rd one and the 8th one.
got the first part of 3rd but not getting the rest.. plzzz help
does anybody know the 8th one?
can u give me brief equations on solving this oil drop?
fine its here
r^3=3*(C1)^2/(4*pi*density*C_2*g)
solve by putting the values given and then,
TAKE THE CUBE ROOT OF THE VALUE YOU OBTAINED.
***the end***
oscillating block ans D) 1.2
