List out (calculate) the initial and final velocities, the
initial and final momentums, the impulse, and the amount of force
required for the change described to occur for the five listed
situations: A car with a mass of 4.0 x 103 kg starts at rest and
accelerates to 40 km/h in one minute (1). It then slams on its
breaks and slows to 5 km/h in 5 seconds (2). It then comes to a
complete stop in 1 second (3)....

A college physics
professor thinks that two of her sections scored differently on the
final exam.
She collects the
scores for the two classes and stores them in a file.
We do not know
anything about the test score distributions.
Answer the following.
Use alpha = 0.05.
a). What is the value
of the test statistic?
b). What is the
p-value?
c). Is she correct in
stating that the final exam scores from the two sections are not

Explain the behavior of rc beam (load-deflection or
Moment-curvature) under the flexural loading highlighting different
stages of loading till failure; i.e. un-cracked section, cracked
section, service condition, yielding and ultimate loading
condition.
Assume the production of a good involves four stages of
production. If the final retail price of this good is $20, it must
be the case that summing the "value added" for all stages of
production will equal:
QUESTION 13
Psychology Final Question 1
A professor teaches two sections of a Psychology class. The
placement of the enrolled students in the two sections is done
randomly. In Section 1, students are required to participate in
weekly study groups. In Section 2, there is no such requirement.
The data file FINAL.MWX (for Minitab 19) or FINAL.MTW (for Minitab
18) contains the final exam scores of students in these two
sections. Let µ1 and µ2 denote the average score in...
