A stick is resting on a concrete step with 2/7 of its total length ? hanging over the edge. A single ladybug lands on the end of the stick hanging over the edge, and the stick begins to tip. A moment later, a second, identical ladybug lands on the other end of the stick, which results in the stick coming momentarily to rest at ?=36.1∘ with respect to the horizontal
If the mass of each bug is 2.92 times the mass of the stick and the stick is 16.3 cm long, what is the magnitude of the angular acceleration ? of the stick?

A stick is resting on a concrete step with 1/7 of its length
hanging over the edge. A single ladybug lands on the end of the
stick hanging over the edge, and the stick begins to tip. A moment
later, a second, identical ladybug lands on the other end of the
stick, which results in the stick coming momentarily to rest 36.1°
from the horizontal. If the mass of each bug is 2.75 times the mass
of the stick and...

A stick is resting on a concrete step with 1/6 of its total
length ? hanging over the edge. A single ladybug lands on the end
of the stick hanging over the edge, and the stick begins to tip. A
moment later, a second, identical ladybug lands on the other end of
the stick, which results in the stick coming momentarily to rest at
θ=62.1∘ with respect to the horizontal, as shown in the figure.

A uniform stick, mass m and length l, is placed in a horizontal
plane by hanging it from a massless string attached to the center.
A ball of mass M moving with speed V in the plane of the stick. The
ball strikes the stick at a distance d from the center. the
collision is elastic. Find the resulting translational and
rotational speeds of the stick and the resulting speed of the ball.

A stick of length L moves past you, parallel to its length, at
speed v. Let your frame be S, and the stick's frame be S'. Call the
event when the front of the stick passes you Event A, and the event
when the back of the stick passes you Event B.
Draw the Minkowski diagram to scale, including both frames, and
putting in both events.

We are given a stick that extends from 0 to x. Its length, x, is
the realization of an exponential random variable X, with mean 1.
We break that stick at a point Y that is uniformly distributed over
the interval [0,x].
Write down the (fully specified) joint PDF fX,Y(x,y) of X and
Y.
For 0<y≤x:
fX,Y(x,y)=
Find Var(E[Y∣X]).
Var(E[Y∣X])=
We do not observe the value of X, but are told that Y=2.2. Find
the MAP estimate of X based...
