Question 4.10 Solution(Mastering Physics Chapter 04: Force and Motion)

Part A

A brick hits a glass window. The brick breaks the glass, so:

  • The magnitude of the force of the brick on the glass is greater than the magnitude of the force of the glass on the brick.
  • The magnitude of the force of the brick on the glass is equal to the magnitude of the force of the glass on the brick.
  • The magnitude of the force of the brick on the glass is smaller than the magnitude of the force of the glass on the brick.
  • None of the preceding

Expert Solution

Part A Answer

Newton’s 3rd Law says that for every action, there is an equal and opposite reaction. So, options A and C are incorrect. Option B is correct according to Newton’s 3rd law (equal and opposite forces). So option D is wrong and:

The magnitude of the force of the brick on the glass is equal to the magnitude of the force of the glass on the brick.

Hanging Chandelier Solution(Mastering Physics Chapter 04: Force and Motion)
A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn’t attach the cables to the ceiling directly above the chandelier. Instead, they attached the cables to the ceiling near the walls. Cable 1 has tension T1 and makes an angle of θ1 with the ceiling. Cable...
Motion of a Block with Three Forces Solution(Mastering Physics Chapter 04: Force and Motion)
