Is a system of two objects in space which are so close that their gravitational interaction causes them to orbit about a common center of mass.
Answer:
6.40 m/s
Explanation:
Here we have to consider the conservation of energy
Potential energy of a object = Kinetic Energy
Mgh = 1/2 M (v)2
V = root 2gh
V = root 2*10*20.5
V = 6.40 m/s
- 1. The value of m is 3.735
2. The value of n is 7
<h3>What is momentum? </h3>
Momentum is defined as the product of mass and velocity. It is expressed as
Momentum = mass × velocity
<h3>How to determine the value of m and n</h3>
We can obtain the value of m and n by simply obtaining the momentum in scientific notation. This is illustrated below:
- Mass of train = 4.5×10⁵ Kg
- Velocity of train = 8.3×10¹ m/s
- Momentum =?
Momentum = mass × velocity
Momentum = 4.5×10⁵ × 8.3×10¹
Momentum = 3.735×10⁷ Kg⋅m/s
Thus, the value of m and n are: 3.735 and 7

Newton’s third law is a force is a push or pull that acts upon an object as a result of another object.. A shot gun when fired pulls back when a force (you pulling the trigger) is acted upon it. This is how it relates. A rifle has less kick than a shot gun because the rifle is smaller and has less of a force than a shot gun.
