(Originais Teachy 2023) - Question Medium of Physics

A simple pendulum is set up in a physics laboratory to determine the local acceleration due to gravity. The object suspended on the pendulum is displaced from its equilibrium position and released. It is observed that the pendulum completes one cycle with a period (T) of 2 seconds and a maximum amplitude of oscillation of 10 cm. Considering that the motion of the suspended object is Simple Harmonic Motion (SHM), answer the following questions. a) Determine the equation of SHM that describes the displacement of the object as a function of time. b) Calculate the maximum velocity of the object during its oscillation. c) Find the local acceleration due to gravity using the results from the previous questions and the formula for the period of a simple pendulum.

Question 1:

Medium

During a visit to a physics laboratory, the students observed an experiment with a simple pendulum. The pendulum consists of a string of length L and a small sphere at the end. The pendulum starts to oscillate smoothly after being displaced from its initial position. First, investigate the relationship between the period of oscillation (T) and the length of the string (L). Then, determine the value of gravity (g) in the region where the pendulum is located, knowing the length of the string and the period of oscillation measured during the experiment. Finally, calculate the length of the string if a different period of oscillation is desired.

Question 2:

Maria is studying at home and decides to conduct an experiment using a simple pendulum, composed of a string of length L and a small sphere at the lower end. She measures the time it takes for the pendulum to complete 10 full oscillations and obtains a value of 22.5 s. Knowing that the acceleration due to gravity in the city where Maria lives is approximately 9.8 m/s², answer: (a) Calculate the period T of a single oscillation of the pendulum. (b) Use simple harmonic motion to determine the length L of the string. (c) If Maria wanted to increase the period of the pendulum by 10%, what new length of string should she use?

Question 4:

João is conducting a Physics experiment in his room with a flat mirror and a beam of light. He positioned the mirror inclined relative to the beam of light. When the mirror is rotated at a specific angle, the reflected beam of light moves and hits a different point on the wall. Given that the mirror is rotated 30° clockwise from its initial position, calculate the rotation angle of the reflected beam and the new position of the reflected beam. a) Determine the rotation angle of the reflected beam when the mirror is rotated 30° clockwise. b) If the wall is 2 meters away from the mirror and the reflected beam of light initially hits a point 1 meter high, calculate the new height of the point hit by the reflected beam of light on the wall after the mirror rotation. c) Calculate the horizontal distance between the initial position of the reflected beam on the wall and the new position after the mirror rotation.
