So the total energy of our system at any moment will be the kinetic energy of the puck (KE = mv² where m is the puck's mass and v is the velocity of the puck) plus the gravitational potential energy of the puck due to the Earth's attraction ( PE, = mgh where his the vertical height of the center of the puck, g is 9.8 m/s2). For simplicity, let's assume that y=0 when the puck is on the level surface before going up the hill. So which of these statements would summarize how we might analyze this situation? The total energy of the system is largest when the puck is sliding along the bottom, because that is when there is the most movement in the system. When the puck reaches its highest point and momentarily stops, the system has no energy. The total energy of the system remains the same at all times. When the puck is siding at the bottom the energy of the system is all kinetic energy and when it reaches its highest point and momentarily stops, all the energy is gravitational potential energy. The kinetic energy of the system is always the same. The potential energy of the system is largest when the puck reaches its maximum height.

1. It's 5:00 PM and Kurdapya needs to finish her physics module, one of the problems tates that a rocket and a spacecraft were attached and has a combined mass of 3.8 × 10⁵kg and is to reach a speed of 12.3 km/s, she needs to know how much kinetic energy will it have. 2. The next day, Kurdapya craved for some riped guava fruit. She has to climb the guava tree however she realized that she is already 65 kg and the tree is 7.2 meters high. Let us calculate the power required for her to climb the tree in 15 seconds.
A spaceship with m = 1.00 ✕ 104 kg is in a circular orbit around the Earth, h = 800 km above its surface. The ship's captain fires the engines in a direction tangent to the orbit, and the spaceship assumes an elliptical orbit around the Earth with an apogee of d = 3.00 ✕ 104 km, measured from the Earth's center. How much energy (in J) must be used from the fuel to achieve this orbit? (Assume that all the fuel energy goes into increasing the orbital energy and that the perigee distance is equal to the initial radius.)
Consider the observation that the acceleration due to the gravitational force acting on a mass around a host planet decreases with the square of the separation between the objects. We can ask ourselves: why is it still accurate to consider a gravitational acceleration value of 9.8\frac{m}{s^2}9.8s2m for all of our projectile motion problems and all of our gravitational potential energy from prior modules? Let's analyze a situation and justify this analysis method: consider an object being launched from ground level to an altitude of 10,000 meters, roughly the cruising altitude of most jet liners, and far above our everyday experiences on Earth's surface. Compare the gravitational acceleration of the object at Earth's surface (the radius of Earth is about r_E=6.37\times10^6mrE=6.37×106m) to the acceleration value at the 10,000 meter altitude by determining the following ratio: g10,000m/gsurface

The radius of the Moon is 1.74×106 m.At what speed ?impact will the asteroid be traveling when it impacts the lunar surface if it is heading straight toward the center of the Moon? How much work ? does the Moon do in stopping the asteroid if neither the Moon nor the asteroid heats up in the process?
A planet of mass M is in an orbit of eccentricity e = 1 – α where α << 1, about the Sun. Assume that the motion of the Sun can be neglected and that only gravitational forces act. When the planet is at its greatest distance from the Sun, it is struck by a comet of mass m, where m << M, traveling in a tangential direction. Assuming that the collision is completely inelastic (that is, the planet and the comet becomes a single body after the collision), find the minimum kinetic energy the comet must have to change the new orbit to a parabola.

Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 km (or even higher) above the surface. Io has a mass of 8.93×1022kg and a radius of 1821 km. For this calculation, ignore any variation in gravity over the 500 km range of the debris. How high would this material go on earth if it were ejected with the same speed as on Io?
