The kinetic energy equation says that KE 12 m x v 2. It supports concepts presented in the short film The Day the Mesozoic Died.

86400 seconds Velocity of Earth v_e.

Calculate kinetic energy of asteroid impact. E impact 66 x 10 21 J E quake8 2 x 10 18 J E Hiroshima 79 x 10 13 J The asteroid impact is 3300 times more energetic than the magnitude 8 earthquake it is equivalent to a magnitude 935 earthquake while the bomb explosion produces only a miniscule amount of energy compared to either the earthquake or asteroid impact. The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash. Peak impact force by multiplying the resulting average impact force by two.

You do this by calculating the kinetic energy of the asteroid just before it strikes the earth. 464 ms Kinetic Energy. M is the mass of the asteroid just before it strikes the earth V is the velocity of the asteroid just before it strikes the earth For.

The activity begins with students watching the film which describes the discovery of a layer of clay at the boundary. You may change any input value and recalculate. Angle of Asteroid Impact from Earths Vertical.

KE kinetic energy in J released by the impact of the meteorite D diameter in meters of the resulting crater This will enable us to calculate KE of impact for any Earth crater of known diameter such as Meteor Crater. If an object of mass mkg is dropped from height. To calculate the kinetic energy first convert kmh to meters per second.

40kmh 1111 ms. The kinetic energy carried by an asteroid equals KE12mV 2 which is huge when the mass gets large. 25MR2 Moment of Inertia.

K12mv2 Potential Gravitational Energy. To operate the calculator enter desired values to describe an impactor and press the Calculate button. Its kinetic energy equals 2500 J way above 1 J because of the considerable velocity.

Here are the steps to follow when using this convenient online tool. 5000 kgm 3 x 5000 m 2 x 10000 m 4 x 10 15 kg. Conducted to estimate the mass and size of the K-T asteroid based on the total abundance of iridium in the K-T boundary layer.

The kinetic energy just before impact is equal to its gravitational potential energyat the height from which it was dropped. LrotIw Moment of Inertia of a Sphere. Thats the reason why bullets cause a lot of damage while hitting targets.

Kinetic Energy 12MV 2 Where. This activity allows students to calculate the mass size and kinetic energy of an asteroid that struck Earth 66 million years ago based on the total abundance of iridium in a sediment layer. You can easily estimate the impact energy of an asteroid.

For example if a an object with a mass of 10 kg m 10 kg is moving at a velocity of 5 meters per second v 5 ms the kinetic energy is equal to 125 Joules or 12 10 kg 5 ms 2. Well it will still hurt when it impacts a body but it definitely wont cause. Let the density of the asteroid be five times the density of water ie 5000 kgm 3.

A 20-km asteroid has just been predicted to hit Earth and you want to know if a. Then enter the value of the Velocity and choose the unit of measurement from the drop-down menu. In classical mechanics kinetic energy KE is equal to half of an objects mass 12m multiplied by the velocity squared.

KEY CONCEPTS AND LEARNING OBJECTIVES. The typical velocity of an asteroid in an Earth-crossing orbit and in the vicinity of Earth is about 20 kmsec. First enter the value of the Mass then choose the unit of measurement from the drop-down menu.

However our ultimate target so to speak is the volume of the meteorite and for that we will need two more equations. 30 degrees Period of Earths Rotational Angular Momentum T. To clear the input windows press the Clear button.

And the kinetic energy traveling at 30000 mph 1 x 10 4 msec is. The 1908 Tunguska collision in Siberia involved an asteroid of about 30 meters in diameter and the Chicxulub collision near the Yucatan some 65 million years ago was produced by an asteroid believed to have a diameter of 10 km. Using the first kinetic energy equation above replace the values for m and v and get KE 2200 1111 2 2 1357753 Joules or 1357753 kiloJoules.

After entering both values the. UGMmr Rotational Angular Momentum. Then the mass of the asteroid is.

H m then the velocity just before impact is. The formula can easily be extended to calculate the approximate maximum impact force aka. Squaring the velocity makes a large number like 20 kmsec much much larger.

Use the kinetic energy calculator to find out how fast that the same bullet will have to be traveling at to get its energy to 1 J. This is equal to the impact energy. 12 x 4 x 10 15 kg x 1 x 10 4 msec 2 2 x 10 23 joule.

The size of the asteroid will then be used to estimate the kinetic energy of the meteorite as it struck Earth and compare the amount to that of other high-energy events. Its a velocity of about 20 ms. Calculate the Effect of an Asteroid Impact on Earth.

A ball which weighs 500.
