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 drawing illustrates. The spring constant of the spring is 325 N/m. The coefficient of kinetic friction between the lower block and the table is 0.600, and the coefficient of static friction between the two blocks is 0.900. A horizontal force F 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,  (a) Draw the FBD for the 30.0 kg block. (b) Find the amount by which the spring is compressed. (c) Determine the magnitude of the force. Show all work and write your answer on your paper and upload it to Gradescope at the end of the exam. Each part is worth 10 points.

The figure shows a uniform crate resting on a horizontal surface. The crate has a square cross section and a weight of W = 580 N, which is uniformly distributed. At the bottom right edge of the surface is a small obstruction that prevents the crate from sliding when a horizontal pushing force P is applied to the left side. However, if this force is great enough, the crate will begin to tip and rotate over the obstruction. (a) What causes the tipping—the force  or the torque that it creates? Explain your answer. (5 points)  (b) Where should P be applied so that a minimum force will be necessary to provide the necessary torque? In other words, should the lever arm be a minimum or a maximum? Explain your answer. (10 points) (c) Determine the minimum pushing force that leads to tipping. (10 points) Show all work and write your answer on your paper and upload it to Gradescope at the end of the exam.
