A 0.58 kg toy airplane is suspended from the ceiling by a 1.6 m long cord and rotates in a horizontal circle. If the cord makes an angle of 35 degrees with the vertical, A. Find the speed of the plane. B. Find the tension in the cord. C. If the speed of the airplane is slowly increased, and the cord will break when the tension reaches 8 N, how fast is the airplane moving, and at what angle is the cord from the vertical when it breaks?
