1. The problem statement, all variables and given/known data A toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with a constant speed of 1.01 m/s in a horizontal circle, as illustrated in the figure. If the angle the string makes with the vertical is 38°, and the tension of the string is 1.1N: (a) Find the radius of the horizontal circle of the plane b) Find the mass of the plane. 3. The attempt at a solution Im having problems understanding how to attack physics problems a point in the right direction would help! I think Im supposed to split this into components using the angle. I drew a FBD with only tension and mg as acting forces. Do I use Newtons 2nd law?
