Consider a system of two particles in the xy plane: m1 = 1.95 kg
is at the location r with arrow1 = (1.00î + 2.00?) m and has a
velocity of (3.00î + 0.500?) m/s; m2 = 3.15 kg is at r with arrow2
= (?4.00î ? 3.00?) m and has velocity (3.00î ? 2.00?) m/s.

An important statistical measurement in service facilities (such
as restaurants and banks) is the variability in service times. As
an experiment, two bank tellers were observed, and the service
times for each of 100 customers were recorded. Do these data allow
us to infer at the 5% significance level that the variance in
service times differs between the two tellers? Estimate with 95%
confidence the ratio of variances of the two bank tellers. Teller 1

Four masses are located on x-y plane as shown in the figure.
Masses m1 = m, m2 = 2m, m3 = 4m and m4 = 8m. The (x,y) coordinates
of mass m1 is (2.0 cm, 0.0 cm). All the masses are located at the
corners of a 3.0 cm x 2.0 cm rectangle. The coordinates of the
center of mass of the system (xcm, ycm) is A. (1.6 cm, 3.2 cm) B.

Three small spherical masses are located in a plane at the
positions shown below. dynamically generated plot The masses are
Q=0.300 kg, R=0..600 kg, and S=0.500 kg. Calculate the moment of
inertia (of the 3 masses) with respect to an axis perpendicular to
the xy plane and passing through x=0 and y=-3. [Since the masses
are of small size, you can neglect the contribution due to moments
of inertia about their centers of mass.]

0.0) m, 3.1 kg at (0.0, 3.6) m, and 4.0 kg at (2.7, 0.0) m. Where
should a fourth object of 7.4 kg be placed so that the center of
gravity of the four-object arrangement will be at (0.0, 0.0) m?

We wish to determine the impact of Specification Buying, X11, on
Satisfaction Level, X10. To do so we will split the Hatco data file
into two separate data sets based on the Specification Buying, X11.
This variable has two categories:
1=employs total value analysis approach, evaluating each
purchase separately;
0 = use of specification buying.
Sort the entire Hatco data set based on Specification Buying.
This will create two separate groups of records. Those records with
X11 = 0 and...
