9) An airplane turns by "banking"; if it's at constant speed, thethrust force from the propellers (or jet engines) just cancels thedrag force resisting the direction of motion. The remaining forcesare the lift force, which is perpendicular to the wings, and gravity. A) While the plane is banking, describe the origin of the centripetalforce that makes the airplane turn in a large horizontal circle. B) If the plane goes 240 km/hr (the cruising speed of the ~1930Ford Trimotor pictured) and the bank angle shouldn't exceed 35 degrees, what is the minimum turning radius (radius of thecircle it will make if it turns 360 degrees)?

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination. at the turning point, how far is the second student from the destination?

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
