Answer:
98.13m
Explanation:
Complete question
Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building
CHECK THE ATTACHMENT
From the figure, using trigonometry
Tan(θ ) = opposite/adjacent
Where Angle (θ )= 63°
Opposite= X = height of the building
Adjacent= 50 m
Then substitute the values we have
Tan(63)= X/50
1.9626= X/50
X= 1.9626 × 50
X= 98.13m
Hence, the height of the building is 98.13m
The kinetic energy of a mass oscillating on a vertical spring is at a minimum when the object is at the extreme points of its motion. This is because the object has momentarily stopped moving, leading to zero kinetic energy. All the energy is instead stored as potential energy in the spring.
In the case of a mass oscillating on a vertical spring, the kinetic energy of the object is at a minimum when the object is at its extreme points, i.e., when it is at points 'a' or 'b'. This is because, at these positions, the object momentarily comes to rest before reversing its direction, thereby having a velocity (and hence kinetic energy), which is proportional to the square of the velocity, of zero. The energy at these points is mainly stored in the spring as potential energy.
At these extreme points, we have a situation where the potential energy (U) is maximum and the kinetic energy (K) is equal to zero. At the midpoint position x = 0, the entire energy is kinetic while the potential energy in the spring is zero, which suggests that the kinetic energy is minimum at the extreme positions.
This property of kinetic and potential energy fluctuating between each other is a common characteristic of simple harmonic motion.
