Answer:
Maximum height reached by the rocket, h = 202.62 meters
Explanation:
It is given that,
Initial speed of the model rocket, u = 56.5 m/s
Constant upward acceleration,
Distance traveled by the engine until it stops, d = 198.8 m
Let v is the speed of the rocket when the engine stops. It can be calculated using the third equation of motion as :
v = 63.02 m/s
At the maximum height, v = 0 and the engine now decelerate under the action of gravity, a = -g. Let h is the maximum height reached by the rocket.
Again using third equation of motion as :
h = 202.62 meters
So, the maximum height reached by the rocket is 202.62 meters. Hence, this is the required solution.
360.67 is the speed of waves on a violin string of mass 707 mg and length of 21.4 cm if the fundamental frequency is 867 Hz.
Mass per unit length of string н = mass/length
= 505×10⁻⁶ kg/ 0.204 m
= 2.47×10-³ kg/m

Fundamental frequency ∫о=884 Hz
a. Speed of waves v = 2L∫о
= 2×0.204 m x 884 Hz
=360.67 m/s.
For example, if the fundamental frequency is 50 Hz (also called the first harmonic), the second harmonic is 100 Hz (50 * 2 = 100 Hz), and the third harmonic is 150 Hz (50 * 3 = 150 Hz ). Such.
The fundamental frequency is the lowest frequency of the resonant system. This is an important concept in many aspects of musical instruments and engineering. For example, all harmonics of a particular wave are based on the fundamental frequency.
