- A jet airplane is in level flight. The mass of the airplane is ?=8990 kg.m=8990 kg. The airplane travels at a constant speed around a circular path of radius ?=9.33 miR=9.33 mi and makes one revolution every ?=0.123 h.T=0.123 h. Given that the lift force acts perpendicularly upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane?The curved section of a horizontal highway is a circular unbanked arc of radius 520 m. If the coefficient of static friction between this roadway and typical tires is 0.30, what would be the maximum safe driving speed for this horizontal curved section of highway?A pilot of mass 75 kg takes her plane into a dive, pulling out of it along a circular arc as she nears the ground, If the plane is flying at 1.5 × 107 km/h along the arc, what is its radius such that the pilot feels four times heavier than normal? Provide an appropriate free-body diagram.
- A sample of blood is placed in a centrifuge of radius 14.0 cm. The mass of a red blood cell is 3.0 ✕ 10−16 kg, and the magnitude of the force acting on it as it settles out of the plasma is 4.0 ✕ 10−11 N. At how many revolutions per second should the centrifuge be operated???????? rev/sA 3,000-kg truck leaves a freeway on a circular exit of radius 50 m at a speed of 15 m/s.

Include anFBD of the car along with the components of the relevant force
- An airplane is flying in a horizontal circle at a speed of 480 km/h. If its wings are tilted at angle u = 40to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface.A small object with mass of 0.5kg is attached to the lower end of a long string and moves in a horizontal circle of radius 0.7 m with a constant speed of 3 m/s. What angle does the string make with the vertical?A cat dozes on a stationary merry-go-round, at a radius of 5.40 m from the center of the ride. Then the operator turns on the ride and brings it up to its proper tuning rate of one complete revolution every 6.00 s. What is the least coefficient of static friction between the cat and the merry-go-round that will allow the cat to stay in place when it is to the right of the center of the ride, without sliding? The directions of the three forces and the acceleration must be identified. Make a free-body diagram. Please use the blue vector to specify forces and the pink vector for acceleration. Assume that the center of rotation is to the left. DO NOT forget to label each vectors with none, mg, T, a, or FN
