Two blocks A and B have a weight of 11 lb and 6 lb, respectively. They are resting on the incline for which the coefficients of static friction are μA = 0.14 and μB = 0.26. Determine the incline angle θ for which both blocks begin to slide. Also find the required stretch or compression in the connecting spring for this to occur. The spring has a stiffness of k = 1.9 lb/ft. (Figure 1) Part A Determine the incline angle θ for which both blocks begin to slide. Express your answer to three significant figures and include the appropriate units. Part B Determine the change of the length of the spring. Assume this change to be positive if the spring is stretched and negative if the spring is compressed. Express your answer to three significant figures and include the appropriate units.

A 13.0 kg stone slides down a snow-covered hill (Figure 1), leaving point A at 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 2.10 N/m. The coefficients of kinetic and static friction between the stone and the horizontal ground are 0.20 and 0.80 , respectively. Figure 1 of 1 Part A What is the speed of the stone when it reaches point B? Express your answer in meters per second to three significant figures. v2 = m/s Submit Request Answer Part B How far will the stone compress the spring? Express your answer in meters to three significant figures. x = Submit Request Answer Part C Will the stone move again after it has been stopped by the spring? yes no
