A jet is flying straight and level at a speed v0 = 1300 km/h when it turns to change its course by 90° as shown. In an attempt to progressively tighten the turn, the speed of the plane is uniformly decreased in time while keeping the normal acceleration constant and equal to 8g, where g is the acceleration due to gravity. At the end of the turn, the speed of the plane is vf = 800 km/h. Determine the radius of curvature ρf at the end of the turn and the time tf that the plane takes to complete its change in course. The radius of curvature ρf at the end of the turn is ___ m.(Round the final answer to one decimal place.) The time tf that the plane takes to complete its change in course is ___ s. (Round the final answer to four decimal places.

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.
