The mass of the bullet moving at the given values of velocity and kinetic energy is 6.4 × 10⁻⁴ kilogram.
<h3>What is Kinetic Energy?</h3>
Kinetic energy is simply a form of energy that a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given the data in the question;
- Velocity of the bullet v = 970m/s
- Kinetic energy of the bullet K = 3.0 × 10³J = 3000kgm²/s²
- Mass of the bullet m = ?
We substitute our given values into the expression above.
K = (1/2)mv²
3000kgm²/s² = 0.5 × m × (970m/s)²
3000kgm²/s² = 0.5 × m × 940900m²/s²
3000kgm²/s² = m × 470450m²/s²
m = 3000kgm²/s² ÷ 470450m²/s²
m = 0.00064kg
m = 6.4 × 10⁻⁴kg
Therefore, the mass of the bullet moving at the given values of velocity and kinetic energy is 6.4 × 10⁻⁴ kilogram.

The subduction zone is the zone in the crust of the Earth where tectonic plates meet.
Magma is a hot fluid formed in the crust. This fluid is the one from which lava is formed.
Most magma that is formed in this region never reaches the surface. However, if it does, belts of volcanoes will be formed.
The doppler effect is when waves’ wavelengths get squished when the source is moving toward you or stretched when the source is moving away from you. it can be observed with sound waves but not light waves because the speed of light is just too fast, meaning that we can’t move toward or away fast enough. (also some stuff with relativity).
The extratropical zone reaches an occlusion. This is the time when the storm weakens after the central pressure begins to subside and then slowly becomes colder. The change lowers the high temperature when the cold front gets over the warm front.
