Metrology of surface finish

In general terms, the application of scientific principles in the study of measurements is known as metrology. When speaking about measurement, it could be of time, length, microstructures, grain structures, internal crystal discontinuities, surface roughness, measurements of angles, height, width, and so on. While coming to the domain of mechanical engineering, metrology is considered the science of measurements of surface finish, length, surface texture, and angles.

How are Slope and Displacement be determined by the integration method?
A gun is on the same horizontal level as a target 484 meters away. A bullet is fired from the gun with a muzzle velocity of 154m/s. At what angle of elecation should the muzzle of the gun be set in order to ensure the bullet hits the target? Hint: You may use the formulas for the horixzontal x(t) and vertical y(t) displacement of the particle: x(t) = ucos(α)t, y(t) - usin(α)t - ½gt2 , g = 10m/sec2.
