A 15.0 kg stone slides down a snow-covered hill, leaving point A at a speed of 10.0 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 2.0 N/m. The coefficients of kinetic friction between the stone and the horizontal ground is 0.2 . A. What is the speed of the stone when it reaches point B? (3 marks) B. How far will the stone compress the spring? (6 marks)

Q2 (Ch7/8) (Solve this with the concept of energy and force) Object of mass M = 15.0 kg moving on horizontal surface. Object velocity at point A is VA = 8.50 m/s. There is μ = 0.350 kinetic friction on horizontal plane. AB = 5.50 m and BC = d = unknown. The acceleration due to gravity is g. a) Consider AB motion and find an algebraic equation for the velocity of the object when it reaches point B and then find the numerical value? (4 points) b) Object touches the spring with spring constant k = 195 N/m at point B. Then the object compresses the spring from B to C(BC = d = unknown) and finally object comes to rest at C. By considering BC motion build a quadratic equation for distance d. (3 points) c) By applying general solution find numerical value for spring compress distance d. (3 points)
