2. Bojana is sliding down a snowy hill on a toboggan. The mass of Bojana and the toboggan together is 41.2 kg. When she reaches a speed of 3.86 m/s, she decides to stick her feet into the snow to reduce her acceleration. From the time she sticks her feet in the snow until she puts them back on the toboggan, she travels a distance of 29.8 m and has a final speed of 6.79 m/s.
