- A planet with a radius of 6.00 × 107 m has a gravitational field of magnitude 40.2 m/s2 at the surface. What is the escape speed from the planet? ____km/sWhite dwarf stars are produced by the collapse of regular stars, such as our sun, toward the end of their normal life. Suppose a star initially has the same mass as our sun and the same radius as that of the sun. Suppose further that it collapses into a white dwarf with a radius of 5000km. If the initial period of the star is the same 27 day period of our sun, what is the resulting period of the white dwarf?n IT'S ARMAGEDDON! A Texas sized asteroid is headed for Earth! You've been hired by NASA to be part of a misfit team of deep-core drillers to save the planet! As the engineer (and most educated person) on the team, you've been tasked with doing the calculations to make sure the Earth will be saved. The plan is to land on the 6.1 x 10²1 kg asteroid traveling at 9830 m/s and detonate a nuclear bomb. The asteroid will break into two pieces of equal mass. One piece will fly off at an angle of 30° and speed 9700 m/s. What will be the speed and angle of the second piece? Scientists estimate that as long as the angle is greater than 15° we're all gonna be alright! Note: This is a totally ridiculous scenario, but the movie made a lot of money and had a lot of famous people in it. Typical Hollywood, right? Note 2: I made up the numbers, but they're close to what the movie describes. m/2,v2 0 m/2, v1 m, vi
- A small asteroid that has a mass of 150 kg is moving at 500 m/s when it is 950 km above the surface of the Moon. The radius of the Moon is 1.737E6 m and the mass of the Moon is 7.350E22 kg. a.How fast will the meteorite be traveling when it impacts the lunar surface if it is heading straight toward the center of the moon? b.The atmosphere of the Moon is negligible. How much work does the Moon do in stopping the asteroid?Please answer step by step.
