Answer:
Acceleration = 0.2m/s²
Explanation:
Given the following data;
Mass = 1000kg
Force = 200N
To find acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation;
Acceleration = 0.2m/s²
Answer:
Explanation:
The universal law of gravitation is defined as:
(1)
Where G is the gravitational constant, M and m are the masses of the two objects and r is the distance between them.
The centripetal force can be found by means of Newton's second law:
(2)
Since it is a circular motion, the acceleration can be defined as:
(3)
Where v is the velocity and r is the orbital radius.
Replacing equation (3) in equation (2) it is gotten:
(4)
Hence,
Then, v can be isolated:
So the relationship between speed and orbital radius is given by the expression
