What's an example equation of an egg rolling down a ramp into a bucket. What's the transfer of energy?

Suppose that you and two classmates are discussing the design of a roller coaster. One classmate says that each summit must be lower than the previous one. Your other classmate says this is nonsense, for as long as the first one is the highest, it doesn’t matter what height the others are. What do you say?

When a driver applies the brakes to keep a car going downhill at constant speed and constant kinetic energy, the potential energy of the car decreases. Where does this energy goes? In contrast, discuss where most of it goes with a hybrid vehicle.

Suppose you are designing a traditional wooden roller coaster. Which is better: having the biggest hill at the beginning of the ride or at the end? Explain your answer in terms of energy (not thrills).

A block of mass 2.0 kg is moving to the left at a constant speed of 3.0 m/s. Match the answers with questions.  What is its initial kinetic energy? What is the change in kinetic energy?

If a moving car applies it's brakes, friction will act on the tires of the car. Does friction do work on the car?

At a circus a performer weighing 90kg is shot from a cannon vertically into the air at 45 m/s. To avoid killing the performer a bar must be hung so that they can grab it at the highest point of their launch. Where should the bar be placed? (Solve using conservation of energy)

We know from the reading that it is possible to move the same object two different distances and still do the same amount of work. Let's consider an example in which Jane pushes a block of ice up an incline while Kip lift the same block of ice vertically to the top of the same incline. See the figure below. (look at picture) We will assume that there is no friction between the surface of the incline and the block of ice. Both of these situations will require the same amount of work and that the result of lifting the ice block to some height imparts potential energy to the ice. In this activity, we will make various calculation to help us better understand the relationship between work and potential energy and the idea of conservation of energy. For this activity we will assume that the mass of the ice block is 5.6 kg and the vertical height of the incline is 2 m. This is the vertical distance that Kip must lift the block of ice. We will assume that the acceleration due to gravity is 10…
