An ideal spring is hung vertically from the ceiling. the spring constant is k = 125 n/m. a block of mass m = 650 g (1000 g = 1 kg) is then attached to the free end and block extends the spring under its weight until it stops moving. calculate the maximum extension of the spring due to the block. (hint: when the system comes to equilibrium, the net force on the block must be zer0.)

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.
