3. A particle of mass 1 kg is dropped into a hole drilled straight through Earth (not through the center). The shortest distance between the hole and the center of Earth is d. Neglecting rotational effects and assume Earth has uniform density. (1) If air resistance is negligible, solve the equation of motion to obtain the displacement of the particle as a function of time.

Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface. 1.What would have to be the mass of this asteroid, in terms of the earth's mass M , for the day to become 27.0% longer than it presently is as a result of the collision? Assume that the asteroid is very small compared to the earth and that the earth is uniform...

Problem 2. In the approximation that the Earth is a sphere of uniform density, it can be shown that the gravitational force it exerts on a mass m inside the Earth at a distancer from the center is mg(r/R), where R is the radius of the Earth. Suppose that there is hole drilled along the diameter straight through the Earth and the air was pumped out of the hole. If UPS dropped a package...

Task 2 (Gravitational Potential of the Earth) In good approximation, the earth can be regarded as a sphere of homogenous mass density with radius R and total mass M. The gravitational potential of a mass m which has a distance r to the center of the earth is given by GMm , r>R U(r) 2R where Eo and G are constants a) Calculate the force F(r) which acts on a mass m at the earth's surface Hint: The gradient of...

1. Teresa Drops a Stone. (Allotted Time - 40 minutes) Teresa drops a stone from rest from the top of an extremely tall building on a huge planet with essentially no atmosphere. You may assume that the stone experiences a constant gravitational acceleration as it falls to the planet’s surface, but the magnitude of this acceleration may not be equal to that on Earth. Let d1 be the distance the rock travels during the 1st second of its fall, let...

Schwarzschild radius (sometimes referred to as the gravitational radius) is the distance from the center of an object such that, if all the mass of the object were compressed within a sphere of such radius, the escape speed from the surface would equal the speed of light. It, thus, defines a spherical boundary called the event horizon, commonly associated with black holes, beyond which the events cannot affect an outside observer. Theoretically, any amount of matter will become a black...

2. (1) A pendulum clock makes use of the fact that the period of a pendulum is consistent and can be predicted relatively easy. What should the length of a pendulum be if the desired frequency of oscillation is. 3. (1) Near the shore, Tsunamis travel at a speed of 30 mph and the distance between crests is about 6.5 miles. What is the frequency of such a wave? Give your answer in units of Hz. When one crest hits...

4. Use Kepler's Second Law and the fact that L-fxp to determine at which points in an elliptical orbit around the Sun a planet has maximum and minimum speeds. (Section 13.5 will help.) 5. At the end of example 13.10, there's an "Evaluate" blurb about how inside the surface of the Earth the force of gravity varies proportionally to the distance from the center, and it makes reference to the next chapter. which is about oscillation. Model the motion of...
