24. A mass-spring system is set up so that the mass oscillates in the horizontal. The mass is 0.88_kg, and the spring has constant 45_N/m. The mass is pulled back so that the spring stretches 0.72 m, and then the mass is released. Find the speed of the mass when it is located at 0.31 m. (Assume there is no friction between the mass and the tabletop.)
A student conducts the "Hooke's Law" Lab with the same apparatus and collects the following data.

A 30.0-kg block is resting on a flat horizontal table. On top of this block is resting a 15.0-kg block, to which a horizontal spring is attached, as the figure illustrates. The spring constant of the spring is 271 N/m. The coefficient of kinetic friction between the lower block and the table is 0.615, and the coefficient of static friction between the two blocks is 0.852. A horizontal force is applied to the lower block as shown. This force is increasing in such a way as to keep the blocks moving at a constant speed. At the point where the upper block begins to slip on the lower block, determine (a) the amount by which the spring is compressed and (b) the magnitude of the force F. www 15.0 kg 30.0 kg F
