    (10) 17. A 10.0 kg block is released from point A in the Figure below. The track is frictionless except for the portion between B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2250 N/m, and compresses the spring 0.300 m from its equilibrium position before coming to rest momentarily. Frictionless forces keep the two blocks from sliding relative to each other, and the two move with the sameacceleration. If F= 1.2 N and M = 1.0 kg, (a) draw free bodydiagram for each block and (b) determine the horizontal component (frictional force ) of the large block on the small block.

  • 7.75 A 0.500-kg block, attached to a spring with length 0.60 m and force constant 40.0 N/ m, is at rest with the back of the block at point A on a frictionless, horizontal air table (Fig. P7.75). The mass of the spring is negligible. You move the block to the right along the surface by pulling with a constant 20.0-N horizontal force. Thus the slope represents the spring constant and has a value of 122.5 N/m. the equilibrium position if the surface that the block resting on is not frictionless but has a coefficient of kinetic In each case the mass moves on a frictionless table and is displaced from its equilibrium position and then released.
