010 (part 1 of 2) 10.0 points A model airplane of mass 0.9 kg is attached to a horizontal string and flies in a horizontal circle of radius 7 m, making 1.2 revolutions every 6 s. (The weight of the plane is balanced by the upward "lift" force of the air on the wings of the plane.) The accelaration due to the gravity is 9.81 m/s². Find the speed of the plane. Answer in units of m/s. 011 (part 2 of 2) 10.0 points Find the tension in the string. Answer in units of N.
Mass m₁ moves in a circular path of radius r on a frictionless horizontal table. It is at- tached to a string that passes through a fric- tionless hole in the center of the table. A second mass m2 is attached to the other end of the string. 1. r = 2. r = Determine an expression for r in terms of m₁, m2, and the period T (the time for one revolution). 3. r = 4. r = 5. r = migT² 2π² m2 m2gT2 7² mi m1972 v m1 4π² m2 m2gT² 4π² m₁ m2gT2 2π² m1 r m2
