A 11.0 kg stone slides down a snow-covered hill, leaving point A with a speed of 12.0 m/s


Part A 

A 11.0 kg stone slides down a snow-covered hill, leaving point A with a speed of 12.0 m/s. There is no friction on the hill between 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 stone travels 100 m and then runs into a very long light spring with force constant k = 250 Nm. The coefficients of kinetic and static friction between the stone and the level ground are 0.26 and 0.78. respectively. How will the stone compress the spring Enter its numerical value only.
