3. Problem 7.49 of Chapter 7. A 15.0-kg stone slides down a snow-covered hill, leaving point A with a speed of 10.0 m/s. There is no friction on the hill between the points A and B, but there is friction on the level ground at the bottom of the hill, between B and the wall. After entering the rough horizontal region, the 20 m stone travels 100 m and then runs into a very long, light spring with force constant 2.00 N/m. The coefficient of kinetic friction between the stone and the horizontal ground is 0.20. 15 m. B Rough MY
