Answer:
A damped oscillation means an oscillation that fades away with time while Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system.
Explanation:
Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. ... When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.

Answer:
The acceleration of the plane is 10.93 m/s² at that instant.
Explanation:
Given:
Mass of aircraft,
Downward thrust produced,
Upward resistance force by air,
Weight of the aircraft acting donward,
According to Newton's second law, net force acting on an object is equal to the product of mass and its acceleration.
Here, the net force is given as the difference of downward forces and upward forces.
Now,
Therefore, the acceleration of the plane is 10.93 m/s² at that instant.
Answer:
U₁ = 129.4 J
Explanation:
The potential energy is
U = mg y - m g y₀
Where I correspond to the initial position, with this it is an additive constant, we can make it zero with the placement of the reference system, in this case the system is placed on the floor where the ladder rests.
The power power for people on the floor is
U₀ = 0 J
The potential energy for the person on the first step is
U₁ = m g y₁
In general the steps are 20 cm high
y₁ = 20 cm (1m / 100cm) = 0.20 m
U₁ = 66 9.8 0.20
U₁ = 129.4 J
