Yes the rod hits horizontally. Do I have to consider the normal force on the mass at the floor.
The Diagram is basically a vertical rod with one end on the floor and the other in the air. both ends have spherical masses attached to them.
Homework Statement
Two heavy balls of equal mass M are attached to the long but light metallic rod standing
on the floor. The rod with the balls falls to the floor. Find the velocity of each ball at the moment
when the rod hits the ground. Neglect mass of the rod and the friction between...
no i have the integral down f(X) becomes y= 1/(e^-x + 2) +C; now the limit of f(x) without the c value is 1/2 which is an asnwer choice; but if i take the limit with c , which is -1/12 b/c the initial condition given is (0, 1/4) the limit becomes .41666667; this however is not an answer choice...
yes, so i have
lim n --> oo ((3x + 4)^(n+1)/ (n +1)) * (n/ (3x +4)^n)
which simplifies to lim (3x + 4) (n/ (n+1))
so is it abs value (3x+4) < 1 if it converges? but i don't think i have this right b/c none of the answer choices fit to make this statement true.
a) 0
b) 1/3
c) 2/3...
yeah i know...
i get the equation
y= 1/(e^-x + 2) +C
without the c value it is 1/2 for the limit
but with the c value which is -1/12 i get a limit of 5/12 which is not an answer choice...
so the question becomes, does the limit depend on the c value or not?
[b]1. The radius of convergence of the power series the sum n=1 to infinity of (3x+4)^n / n is
a 0
b 1/3
c 2/3
d 3/4
e 4/3
[b]2. the sum n=1 to infinity of (3x+4)^n / n
[b]3. no idea
do the ration test to get abs value 3x+4 < 1 ?
HELP! limit and differentials
1. i can't seem to figure this out...
if the differential equation dy/dx= y-2y^2 has a solution curve y=f(x) contianing point (o, 0.25) then the limit as x approaches infinity of f(x) is
a)no limit
b. 0
c. 0.25
d. 0.5
e. 2
he...

sorry about that
so for a i think i have it right since its just asking for the rotational inertia of the 4 spokes. they give the formula for each spoke as ½ ML2; and since the answers are all variables i am assuming its just ½ ML2 + ½ ML2 + ½ ML2 +½ ML2 = total rotational inertia for the...
Can anyone help me with problem 2 on the 2002 free response section for mechanics:
The cart is mass m and has four solid rubber tires each of mass m/4 and radius r. Each tire has rotational inertia ½ ML2. The cart is released from rest and rolls without slipping from the top of an inclined...
