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.

Complete Question
A proton is located at <3 x 10^{-10}, -5*10^{-10} , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton
Answer:
The vector position is
Explanation:
From the question we are told that
The position of the proton is
Generally the vector location of the proton is mathematically represented as
So substituting values
The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
- Momentum of car = 3,000 kgm/s.
- Mass of car = 2,000 kg.
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;
Making velocity the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity = 1.5 m/s.
