Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.

Problem Description You are stuck in an elevator with a meter stick, a spring with a spring constant of 30 N/m, and an object with a mass of exactly 0.5 kg. When you suspend the object from the end of the spring, you find that the spring stretches by 18 cm. Determine everything you can about the motion of the elevator from this information. Instructions In a neat and organized fashion, write out a solution which includes the following: 1. A sketch of the physical situation with all given physical quantities clearly labeled. 2. Represent the forces exerted on the object using a force diagram and, after you have made your determinations about the motion of the elevator, construct possible motion diagrams representing the motion of the elevator (if you think there is only one possible motion draw that, if you think there are several possible motions draw motion diagrams for each of them). 3. Determine everything you can about the motion of the elevator. Use your force diagram and…
Let’s look at a simplified model of a car that’s dropped onto the ground. Model the suspension as a single linear spring and the rest of the vehicle as a single lumped mass. The car is dropped from a height of h1 = 0.9m. What is the maximum mass m for which the suspension does not bottom out? Assume a maximal allowable suspension travel of 10 cm and a spring constant of k = 2.4x10^6 N/m.
