Answer:
Explanation: It is inertia that causes the passengers to move toward the right side of the car. As the car swerves to left, passengers' body continues their motion as hitherto and as such it causes the passengers to move toward the right side of the car.
Here is the energy that is left after the quantity of energy is transformed: 750 j of electrical energy is changed into 400 j of kinetic or mechanical energy, which is then turned into 0.32 j of efficient energy.
To run the fan, electrical energy is utilized.
Here, under the specified circumstances, 750 J of electrical energy is utilized to operate the fan, which is transformed into 400 J of kinetic energy. As a result, 350 J of energy is wasted due to various frictional and resistive losses.
Therefore, we may conclude that only 400 J of the 750 J available energy is used to power the fan, with the remaining energy being wasted as a result of friction.
Additionally, we can state that this fan's effectiveness will be
n = Useful ÷ Total
n = 400 ÷ 750
n = 8 ÷ 25
n = 0.32

Initial amplitude
Final amplitude
Number of oscillation = 4
(a). We need to calculate the time
Given formula,
Put the value into the formula
We need to calculate the value of b
Using damping formula
(b), The damping force equation is
We know that,
The time period is
Therefore, time period is affected by damping force.
Hence, This is the required solution.
