The loon is an aquatic bird that can be found in North America and Eurasia. Loons may live up to 30 years and are capable of reaching speeds of 70 mph in the air. Due to their relatively heavy bodies it takes them some distance to reach lift off speed from the ground. Starting from rest a specific loon takes 105 m in order to reach a launch velocity of 18 m/s. What is the acceleration of the loon in this case?
