Kinetic energy....
1 answer:
Explanation:
Given parameters:
mass of bullet 1 = 0.0014kg
velocity of bullet 1 = 396m/s
mass of bullet 2 = 7.1 x 10⁷kg
velocity of bullet 2 = 13m/s
Unknown;
Comparing the kinetic energy
Solution:
Kinetic energy is the energy due to the motion of a body.
K.E = m v
bullet 1:
K.E = x 0.0014 x 396
= 109.8J
bullet 2:
K.E = 7.1 x 10⁷ x 13
= 6 x 10⁹J
The second bullet has more kinetic energy than the first one.

Answer:
The requested distance is 4320 meters
Explanation:
We can use the formula for velocity in this movement at constant velocity (v), which is defined as the quotient between the distance covered divided the time it took:
Since we know the velocity and the time, we can solve for the distance:
