Question

The mass of a meteor with a radius of 1 km is about 9 x 10^12 kg. The mass of a meteor also is proportional to the cube of its radius. Suppose a meteor with a radius of 11.6 km is moving at 1.6 x 10^4 m/s when it collides inelastically with the Earth. The Earth has a mass of 5.97 x 10^24kg and assume the Earth is stationary. The kinetic energy lost by the asteroid in this collision will be transferred to non-conservative work in heating the atmosphere and physically destroying the place where it lands. The Tsar Bomb, the largest atomic bomb ever tested, released 2.1 x 10^17 J of energy. (Which, by the way, is 1000's of times more energy compared to the atomic bombs dropped in World War II.) How many MILLIONS of equivalent Tsar Bombs is the kinetic energy lost of this meteor?

Answer #1

The mass of a meteor with a radius of 1 km is about 9 x 1012 kg.
The mass of a meteor also is proportional to the cube of its
radius. Suppose a meteor with a radius of 8.1 km is moving at 2 x
104m/s when it collides inelastically with the Earth. The Earth has
a mass of 5.97 x 1024 kg and assume the Earth is stationary. The
kinetic energy lost by the asteroid in this collision will...

The mass of a meteor with a radius of 1 km is about 9 x 1012 kg.
The mass of a meteor also is proportional to the cube of its
radius. Suppose a meteor with a radius of 8.5 km is moving at 2.0 x
104 m/s when it collides inelastically with the Earth. The Earth
has a mass of 5.97 x 1024 kg and assume the Earth is stationary.

The mass of a meteor also is proportional to the cube of its
radius. Suppose a meteor with a radius of 11.4 km is moving at 1.8
x 104 m/s when it collides inelastically with the Earth. The Earth
has a mass of 5.97 x 1024 kg and assume the Earth is stationary.

2.) The mass of a meteor with a radius of 1 km is about 9 x 1012
kg. The mass of a meteor also is proportional to the cube of its
radius. Suppose a meteor with a radius of 10.7 km is moving at 1.7
x 104 m/s when it collides inelastically with the Earth. The Earth
has a mass of 5.97 x 1024 kg and assume the Earth is stationary.

The Little Prince lives on an asteroid with a radius of 10 km
made up of volcanic rock (density 2,500 kg/m3). His mass
is 30 kg. a) What is his weight on the asteroid?
On Earth he can jump to a height of 1 m. With that knowledge, he
jumps up on the asteroid as hard as he can. b) Will he be able to
escape the asteroid?
The mass of the Earth is 6 x 1024 kg. The radius...

A mass of 5 kg is moving at 12 m/s in the +x direction and it
collides inelastically with a mass of 10 kg moving in the -x
direction. The collision takes places in 0.27 seconds and the
average force on the mass moving in the +x direction is 170 Newtons
in the -x direction. How much total kinetic energy is lost in the
collision in Joules? Answer is a positive number since I'm asking
how much is lost.
please...

Scientists believe that during the Mesozoic period a meteor
struck the earth and covered the planet in a layer of sediment
which is rich in iridium. This element is not found in abundance on
earth, but is commonly found in asteroids. In the study of Spanish
soil they found a concentration 30 ng / cm2 of iridium, and let’s
assume28that due to the worldwide impact of such a meteor, the
layer would be equally as concentrated everywhere on the planet....

Space X recently launched Starlink satellites in an orbit of
radius 6850 km. How fast will the satellites be moving in the
orbit? Express your answer in m/s.
Mass of the earth = 5.97 x 10^24 kg
1 km = 1,000 m.
