Problem 3: If a horizontal force P = 12 lb is applied to block , determine the acceleration of the block . Neglect friction. Hint: Acceleration of to the right and acceleration of upward, are ‘related’ to each other!

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

Which model displays the change in a gas when the temperature of the gaseous system decreases?
