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.

Answer:
Explanation:
To start off you need to know that the mass of an object never changes. But gravity does. Think about it life this. Gravity is less on the moon but more on earth, therefore, gravity can change, but mass can't. Now its almost the same as weight because weight changed based upon the gravity. On the moon you weigh only about 10 pounds, on earth, you way much more, and so on.
To calculate the formula you have to do Mass×Gravity which can calculate into Weight.
~Evie weight = mass * gravity
We know that mass never changes, but the weight changes depending on the gravitational pull.
