An
underground military base is designed to withstand up to three
direct hits from air-to- surface missiles. An enemy aircraft armed
with missiles, each having a 30% chance of a direct hit, starts
firing at the base.
What is the expected number of missiles needed to destroy the
base?
Find the variance, standard deviation and the second moment of
the aircraft destroying the base.
Solutions
Expert Solution
Therefore,
Expected number of missiles needed to destroy the base = 0.9 = 1 ( approx. )
Variance = 0.63
Standard Deviation = 0.794 ( rounded up to 3 decimal places )
Second Moment = 1.44

A ball is shot up from a surface that is 20 m above the surface
with an initial speed of 10 m/s.
1. What is the magnitude of the ball's displacement from the
surface after 3.00 second has elapsed?
2. What max height will the ball reach from the surface of the
earth?
3. How much time elapses between the throwing of the ball and
its reaching to the earth?
4. Calculate the magnitude of the velocity of the ball...

1. an undulated surface that is designed to reduce friction by
eliminating wear particles from the sliding interface. The
interface is subjected to normal force N. The sliding speed is so
low that the interfacial temperature rise is negligible relative to
the melting point of the material. We are planning to use metals
for the sliders.
a. Determine the optimum dimensions of the undulated
topography.
b. Discuss the consequence of deviating from the optimum
geometry.
