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
equal to...

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.
