91Ó°ÊÓ

A space station astronaut is working outside the station as it orbits the earth. If he drops a hammer, will it fall to earth? Explain why or why not.

Short Answer

Expert verified

It will NOT fall to earth, rather it will be floating in space.

Step by step solution

01

Given Information

A space station astronaut is working outside the station as it orbits the earth.

He drops a hammer.

02

Explanation

As there is no gravity in the space (assuming no other forces are acting), So the hammer will keep on floating and will Not fall on the earth surface.

In 2014, the European Space Agency placed a satellite in orbit around comet 67P/Churyumov-Gerasimenko and then landed a probe on the surface. The actual orbit was elliptical, but we’ll approximate it as a 50-km-diameter circular orbit with a period of 11 days.
a. What was the satellite’s orbital speed around the comet? (Both the comet and the satellite are orbiting the sun at a much higher speed.)

b. What is the mass of the comet?
c. The lander was pushed from the satellite, toward the comet, at a speed of 70 cm/s, and it then fell—taking about 7 hours—to the surface. What was its landing speed? The comet’s shape is
irregular, but on average it has a diameter of 3.6 km.

A new planet is discovered orbiting the star Vega in a circular orbit. The planet takes 55earth years to complete one orbit around the star. Vega’s mass is 2.1times the sun’s mass. What is the radius of the planet’s orbit? Give your answer as a multiple of the radius of the earth’s orbit.

What are the speed and altitude of a geosynchronous satellite orbiting Mars? Mars rotates on its axis once every 24.8hours.

The escape speed from Planet X is 10,000 m/s. Planet Y has the same radius as Planet X but is twice as dense. What is the escape speed from Planet Y?

FIGURE P13.57 shows two planets of mass m orbiting a star of mass M. The planets are in the same orbit, with radius r, but are always at opposite ends of a diameter. Find an exact expression for the orbital period T. Hint: Each planet feels two forces.
