Work and Energy1. How much work must be done to stop a 1025-kg car traveling at 67kph?
This might be a lot of work and a lot of explaining but I need help creating an energy system diagram like the example below and writing a reasoning summary to explain the final answer to my big question. A new "diet" Phenomenon Your friend Trent is excited about physics because they have discovered they can eat all the shave ice they want without gaining any weight. He says, “I can put just the right amount of flavored syrup on the ice such that I don’t gain any net energy in the process.” You, being a PHYS 2A student, are skeptical and decide to check it out for yourself. You’ll need to model “eating” the shave ice. All the information you need to answer this question can be found here, on the Maybe Useful Information page. The Big Question you are trying to answer is: Do you agree or disagree with Trent’s claim: “I put just the right amount of flavored syrup on the ice such that I don’t gain any net energy in the process.” Your task is to answer the Big Question in the form of an…
YOU MUST ONLY USE ENERGY CONCEPTS TO COMPLETE THE PROBLEMS BELOW. 1. A toy truck with a mass of 78g is travelling at 15.5m/s on a rough surface. If the car is subject to a friction force of 25N, how far will it travel while slowing down to a speed of 2.5 m/s?
What is power? Calculate the power to move a 9 J box in 20 seconds. Calculate the power used for a 500N student to run 3 m in 5 seconds. How much work is used when a 200-Watt machine runs for 30 seconds?
4. How much energy is needed to lift an object that weighs 100 N to a height of 5 meters? (Write first the given and the required quantities then you must show your solution)
A 20.0 kg child is on a swing that hangs from 3.0 m long chains, as shown in (Figure 1). What is her speed vi at the bottom of the arc if she swings out to a 45 degree angle before reversing direction?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 9. When climbing a flight of stairs, do you do work on the stairs? Do the stairs do work on you?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 29. A person runs up several flights of stairs and is exhausted at the top. Later, the same person walks up the same stairs and does not feel as tired. Why is this? Ignoring air resistance, does it take more work or energy to run up the stairs than to walk up?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 13. When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work when throwing the ball, does it go twice as fast? Explain.

Are you doing work right now?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) If we know that a force of 5 N acts on an object while it moves 2 meters, can we calculate how much work was done with no other information? Explain.
