Answer:
Explanation:
First we need to state our assumptions:
Thermal properties of ice and water are constant, heat transfer to the glass is negligible, Heat of ice
Mass of water,.
Energy balance for the ice-water system is defined as
a.The mass of ice at is defined as:
b.Mass of ice at is defined as:
c.Mass of cooled water at
The equilibrium condition allows finding the result for the force that the chair exerts on the student is:
Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.
∑ F = 0
Where F is the external force.
The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.
Let's analyze the force on the chair.
Let's analyze the forces on the student.
In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:
