Chapter 19, Problem 2RQ
An unmanned X-43A scramjet test vehicle has achieved a maximum speed of Mach number 9.68 in a test flight over the Pacific Ocean. Mach number is defined as the speed of an object divided by the speed of sound. Assuming the speed of sound is 343 meters per second, write a MAT LAB program that asks the user to provide a speed as a Mach number, calculates the corresponding speed in miles per hour, and displays the speed in a formatted sentence as shown in the following sample output. Note that the speed in mph should be shown as an integer. If the user provides a negative value for the Mach number, your program should display an error message and terminate.
Enter the speed as a Mach number: -2
Error: The Mach number must not be negative.
Enter the speed as a Mach number: 0
The speed of the plane is 0 mph.
Enter the speed as a Mach number: 9.68
The speed of the plane is 7425 mph.

The net force exerted on the piston by the exploding fuel-air mixture
and friction is 5 kN to the left. A clockwise couple M = 200 N-m acts on the crank AB.
The moment of inertia of the crank about A is 0.0003 kg-m2
. The mass of the
connecting rod BC is 0.36 kg, and its center of mass is 40 mm from B on the line from B
to C. The connecting rod’s moment of inertia about its center of mass is 0.0004 kg-m2
.
The mass of the piston is 4.6 kg. The crank AB has a counterclockwise angular velocity
of 2000 rpm at the instant shown. Neglect the gravitational forces on the crank,
connecting rod, and piston – they still have mass, just don’t include weight on the FBDs.
What is the piston’s acceleration?
