The polar bear is an excellent swimmer, and it spends a large part of its time in the water. Suppose a polar bear wants to swim from an ice floe to a particular point on the shore. The bear dives into the water and begins swimming. As the bear swims, it tires and slows at a rate of 0.0122 m/s/s. By the time it reaches the shore, which is 40.1 m from where it dove into the water, its velocity is 2.13 m/s. How fast was the bear swimming when it first got into the water? ____________m/s
