Answer:
Efriction = 768.23 [kJ]
Explanation:
In order to solve this problem we must use the principle of energy conservation. Where it tells us that the energy of a system plus the work applied or performed by that system, will be equal to the energy in the final state. We have two states the initial at the time of the balloon jump and the final state when the parachutist lands.
We must identify the types of energy in each state, in the initial state there is only potential energy, since the reference level is in the ground, at the reference point the potential energy is zero. At the time of landing the parachutist will only have potential energy, since it reaches the reference level.
The friction force acts in the opposite direction to the movement, therefore it will have a negative sign.
where:
m = mass = 56 [kg]
h = elevation = 1400 [m]
v = velocity = 5.6 [m/s]

Consider the sum of sinusoids de (t) = sin(24(941)t) + sin(27(1336)t)
answer : Value of DFT frequency = 684 Hz
Explanation:
Given data:
sample signal ( Fs ) = 8000 Hz
Fourier transform using an FFT with 4096 points
<u>Determine the value of DFT frequency bins closest to the two frequencies of the sinusoids ( 941 and 1336 Hz ) ( in HZ )</u>
fs = 8000 Hz
4096 parts are divided with a gap of Fs/N
attached below is the detailed solution
