An object rolls without slipping onto a surface where the coefficient of friction between object and surface is twice as great as that needed to prevent slipping. describe the subsequent motion. the object begins to slip, and the actual force of static friction increases. the object begins to slip, and the actual force of static friction doesn't change. the object continues to roll without slipping, and the actual force of static friction doesn't change. the object continues to roll without slipping. and the actual force of static friction increases.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
