An asteroid of mass 156 kg is heading toward Earth with a speed of 110 m/s. How much kinetic energy will the asteroid have when it reaches Earth?

A. 8,580 J
B. 17,200 J
C. 944,000 J
D. 1,560,000 J

Answer :

Final answer:

The kinetic energy of the asteroid as it reaches Earth can be calculated using the formula for kinetic energy, and is approximately 944,000 J.

Explanation:

The kinetic energy of an object can be calculated using the formula KE = 0.5 * m * v^2, where KE represents the kinetic energy, m is the mass of the object, and v is the velocity of the object.

Using this formula, the kinetic energy of the asteroid can be calculated as follows:

KE = 0.5 * 156kg * (110 m/s)^2

This calculation results in the kinetic energy being approximately 944,000 J, which corresponds to option C.
