Question: 1. A 320 N force is applied to a horizontal spring which stretches it by 7 cm cm to the left. What is the spring

1. A 320 N force is applied to a horizontal spring which stretches it by 7 cm cm to the left. What is the spring constant of this spring? 2. A 763 g mass is placed on top of a spring. The other end of the spring is attached to the floor. You also push down on the mass with a force of 2.1 N. The spring moves downward a total of 0.079 m from its equilibrium position. Find the spring constant of this spring. 3. A spring is hanging vertically and has a spring constant of 5730 N/m. An unknown mass is hung from the spring. If the mass causes the spring to stretch by 0.17 m, find the weight and mass of the object. 4. A cube rests on a table. The cube has a mass of 7 kg and each side of the cube is 0.08 m long. What is the pressure of the cube resting on the table?
