1. State Hooks law both in words and equation form 2. Consider the concepts related to springs. Choose one of the following to answer: i. Compare and contrast restoring force and applied force ii. Compare and contrast a real spring and an ideal spring 3. Spring A is harder to stretch than spring B . Explain how the spring dorce constants of each spring would compare in this situation 4. Using the image below as an aid, describe the energy conversions a spring undergoes during a simple harmonic motion as it moves from the point of maximum compression to maximum stretch in a frictionless environment. Be sure to indicate the points at which there will be: i. maximum speed ii. minimum speed iii. minimum acceleration 5. A mass of 4.0kg is in motion along a horizontal, frictionless surface with a speed of 2.5m/s when it makes contact with a horizontal spring anchored to a wall. The spring compresses ans brings the mass to a momentary rest. The Spring's constant is 1250N/m i. Determine the maximum distance the spring is compressed ii. Determine the speed of the block when the spring is compressed a distance of 9.5 cm 6. A toy launcher is used to launch a 10.5g object into the air. The spring of the launcher is initially compressed 6.0 cm. The spring constant of 5.2 x 10^2 N/m i. Determine the elastic potential energy of the compressed spring ii. Determine the speed of the object as it is ejected upward from the launcher
