Answer:
The speed of the block is 4.96 m/s.
Explanation:
Given that.
Mass of block = 1.00 kg
Spring constant = 500 N/m
Position
Coefficient of friction = 0.350
(A). We need to calculate the speed the block has as it passes through equilibrium if the horizontal surface is friction less
Using formula of kinetic energy and potential energy
Put the value into the formula
Hence, The speed of the block is 4.96 m/s.
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.
