Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.

You pull on a string with a horizontal force of magnitude F = 59 N that is attached to a block of mass m = 6.3 kg, then to the axle of a solid cylinder of mass mc = 5.9 kg and radius r = 0.4 m, then to a spring of spring constant k = 145 N/m. This is all done on an inclined plane where there is friction (μ = 0.63 and μ = 0.36), and the incline angle is 0 = 28 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. k bllllllll b 0 Fyb
