1. A spring with a spring constant k = 1600 N/mis at rest on the bottom of an inclined plane. A 7.0-kg blockslides down the plane and makes contact with the spring at point Aas shown. After contact, the spring is compressed to point B, 0.20m from point A, where the speed of the block is zero m/s. What was the speed of the block just before contact with the spring?
2. A cylinder with a diameterof 0.240 m is placed between the plates of a hydraulic press asillustrated in the drawing. A 4.45 × 105-N forceis applied to the cylinder. What is the pressure on the end of the cylinder due to the applied force?
