A Honda N Box car is traveling on the highway at 70 mph (112.6 km/hr). It is a nice summer day with no breeze and the temperature outside is 77F (25C, density = 1.184 kg/m^3, kinematic viscosity = 1.562*10^-5 m^2/s). The roof of the N Box car is 1478 mm wide and 3395 mm long.
Determine how far above the car a bug must fly in order to NOT be affected by the passing car (unit: meters) **accurate to 3 significant digits
Determine the drag force on the roof of the car (Unit: N) **accurate to 2 decimal places

An unmarked police car traveling a constant 95 km/hr is passed
by a speeder traveling 135 km/hr. Precisely 1.00 s after the
speeder passes, the police officer steps on the accelerator; if the
police car’s acceleration is 2.00 m/s2 , how much time passes
before the police car overtakes the speeder (assumed moving at
constant speed)?

For a car that travels 70 mph for 60 miles and then 80 mph for
60 miles. The total time traveled is given by calculating the
distance per rate traveled for each part and then summing the
values. •Have the program in c++ that calculates the most
appropriate mean rate of the two different rates and the two equal
distances, and output the result to the text file. The “best” mean
rate is the rate at which T=D/R is same...

1 – Consider the car-caravan analogy. In this problem, assume a
propagation speed of 70 km/hr and that each toll booth takes 6
seconds to service a car. Suppose the caravan of 10 cars begins
immediately in front of the first toll booth, travels 50 km to a
second toll booth, then another 50 km to a third toll booth, and
finally stops immediately after the third tool booth. Thus, they
travel a total of 100 km. What is the...

A highway being designed to AASHTO guidelines with a 70 mph
design speed, and at one section, an equal tangent vertical curve
must be designed to connect grades of +1% and -2%. If the grades
intersect at station 100+00, determine the stationing of the PVC,
PVT and curve high point for the minimum curve length based pn SSD
requirements.

Consider a car traveling on a highway. If the car travels 100
miles in 2 hours, which theorem guarantees that
the car must have been traveling at 50 mph at some point in those
two hours? (You may assume position and velocity are continuous and
differentiable)

A motorcycle is following a car that is traveling at constant
speed on a straight highway. Initially, the car and the motorcycle
are both traveling at the same speed of 21.5 m/s , and the distance
between them is 60.0 m . After t1 = 5.00 s , the motorcycle starts
to accelerate at a rate of 8.00 m/s2 . The motorcycle catches up
with the car at some time t2.

A motorcycle is following a car that is traveling at constant
speed on a straight highway. Initially, the car and the motorcycle
are both traveling at the same speed of 18.0m/s , and the distance
between them is 54.0m. (A) How long does it take from the moment
when the motorcycle starts to accelerate until it catches up with
the car? In other words, find t2-t1. (B) How far does the
motorcycle travel from the moment it starts to accelerate...

The braking distance for a Krazy-Car traveling at 50 mph is
normally distributed with a mean of 50 ft. and a standard deviation
of 5 ft. Answer the following without using the z table.
a. What is the random variable in this problem?
_______________________________
b. If top 3.5% of the cars are going too fast, what would be the
braking distance?
c. Find Q1, the median, Q3 and IQR.

An unmarked police car traveling a constant 80.0 km/h is passed
by a speeder traveling 135 km/h . Precisely 2.00 s after the
speeder passes, the police officer steps on the accelerator; if the
police car's acceleration is 1.60 m/s2 , how much time passes
before the police car overtakes the speeder after the speeder
passes (assumed moving at constant speed)?
