Answer:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
Explanation:
For this case we have this:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
Answer:
Explanation:
Given
Mass
Spring constant
Compression in the spring
When the mass leaves the spring, the elastic potential energy of spring is being converted into kinetic energy of mass i.e.
The kinetic energy of the mass is 1.102 J.
