- I want the correct answer with explanationA. Calculate the work done by the force of gravity when a 5.0kg object is lifted to a height of 30.0m above the ground B. Calculate the velocity with which the object strikes the ground if dropped from that height, using the principle of conservation of energy C. Calculate the kinetic energy and the potential energy of the object at a halfway on the path after it is dropped. To do this part, you need to find the velocity of the object at that position using an equation of motion. What is the total energy of the object at that point? Does this verify the principle of conservation of energy?A mouse is on a crazy roller coaster which has five distinct phases. The mouse in his roller coaster car has a mass of 6 kg. The mouse starts the coaster by being pulled back 0.2 m into a spring with a spring constant of 1890 N/m. How much elastic potential energy does the mouse have as he starts his ride? After the spring is released, the mouse travels over the first hill, effectively coming to rest at the top. Calculate the height of the first hill? He then speeds into a valley. At the bottom of the valley 3 J of energy is lost due to friction. What is his total remaining energy after he travels through the valley? The mouse then travels over a 0.10 m hill. How fast is the mouse traveling over the hill at point D? The mouse finally makes it to the final phase of the ride, where he will race along at ground level. How fast is he traveling at point E?
- A 0.2 kg ball is resting on edge of the top of a 1 m height table. Does the ball have kinetic energy? Explain. Does the ball have potential energy? What is the value of its potential energy? If the ball falls off the table, what happens to its potential energy and kinetic energy during this falling? Which increases/decreases?Q 3. Three cars are traveling at 30km/h, 50km/h and 200km/h, respectively. Each speed corresponds to a certain kinetic energy. a) Note down the expression for the kinetic energy of a moving object with a velocity v. b) Note down the potential energy for an object lifted up from the ground to height h. c) Based on a) and b) find an expression for the height as a function of velocity by assuming that the kinetic energy equals the potential energy of the same object. In other words find h(v) from which the object would need to be dropped and calculate the height so it has a speed of 30 km/h, 50 km/h or 200 km/h on impact with the ground. Assume free fall without air resistance d) Comment on your chances of survival if you are involved in head-on collisions for the three different speeds.
