A typical feeder may hold 2 kg of seed in a 0.5-meter-long cylinder with a diameter of 6 centimeters. For this exercise, assume that the bottom ring is about 10 cm in diameter. According to the South Carolina Department of Natural Resources, The Eastern Gray squirrel reaches a length of 41 to 51 cm (16 to 20 inches), half of which may be tail. Its weight averages from 0.45 to 0.68 kg (1 to 1.5 pounds). 

1. If a 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, what angular momentum about the feeder axis does the squirrel have at the moment of first contact with the feeder ring.
