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.

A fly walks with a speed of 1 cm/sec in every direction of a piece of paperwhich is considered to be xy plane. If the fly walks away from the origin inthe direction of u = i − 7j, the temperature it measures increases at a rateof 3◦C/sec. If the fly walks away from the origin in the direction v = i + j,the temperature it measures decreases at a rate of 2◦C/sec. Find how fast thetemperature changes if the fly moves away from the origin in the positive x axisdirection.
Your answer is partially correct. The velocity of a particle moving in the x-y plane is given by (7.70i + 4.91j) m/s at time t = 7.38 s. Its average acceleration during the next 0.029 s is (3.3i + 2.6j) m/s?.
