Geodesics equation we are given a metric: (a) calculate the christoffel symbols "by hand". you don't need to show your work for the large group that are obviously zero (but explain which ones they are and why) (b) use (a) to find the geodesic equation (c) re-derive the geodesic by maximizing the proper time where you use the expression for the metric from the beginning (i. e. use this metric in the formula for proper time and then minimize (d) the schwarzschild metric is given in the usual coordinates as expanding around a specific point in space with r »> 2m, show that the metric takes the form of the metric in equation (6) (e) (bonus) from your answer in (d) and intuition for gravity around the earth, what do you think the geodesics that solve (b) should look like?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w
