5. A jet plane flying with the wind went 2275 mi in 5 h. Flying against the wind, the plane could only fly 1750 mi in the same amount of time. Find the rate of the plane in calm air and the rate of the wind. (Round your answers to one decimal place.) rate of plane      ______mph rate of wind     _______ mph

Drag force is an important concept in automobile design. It is modeled as Fa = 0.5PVAC4 where Fa = drag force [lb] air density [slugs/ft³] V = speed of vehicle [ft/s] A = frontal area of car [ft2] Cả = drag coefficient [?] What must be the units for Ca? Show all steps. Break down into fundamental dimensions. Ed

Answer in terms of fundamental units

A man pulls a crate with a rope. The crate slides along the floor in the horizontal direction (x direction). The man exerts a force of 50 N on the rope, and the rope is at an angle 0. Described how the force components (Fx,Fy) change as the angle increases from 0 degrees to 90 degrees and use your graph to explain your answer. Give a detailed explanation of the forces at 0= 0, 45degrees, and 90 degrees. please show a sample calculation at one angle for both components.
