The squirrel holds on with front arms and its body extends outward at an angle to the vertical. Why is that happening, and how you would calculate this angle knowing the rate of rotation and the dimensions of the squirrel and feeder? 

A typical feeder may hold 2 kg of seed in a 0.5 meter long cylinder with a diameter of 6 centimeters, and the mass of the squirrel 0.68 kg. The squirrel leaps toward the feeder at a speed of 4 m/s and reaches the ring with outstretched arms 15 cm from the axis of the feeder cylinder.
