Answer:
2) 433 mph
Explanation:
The final velocity of the raindrop as it reaches the ground can be found by using the equation for a uniformly accelerated motion:
where
v is the final velocity
u = 0 is the initial velocity (the raindrop starts from rest)
a = g = 9.8 m/s^2 is the acceleration due to gravity
d = 2 km = 2000 m is the distance covered
Solving for v,
And keeping in mind that
1 mile = 1609 metres
1 hour = 3600 s
The speed converted into miles per hour is
Calderas are what sometimes surround it
La capital de Puerto Rico es la ciudad "San Juan".
The equation of the motion of this object is ![\mathbf{y = 3 cos \Big [ \dfrac{ \pi}{2}(t -2) \Big ] }](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%203%20cos%20%5CBig%20%5B%20%5Cdfrac%7B%20%5Cpi%7D%7B2%7D%28t%20-2%29%20%5CBig%20%5D%20%7D)
<h3>What is oscillation?</h3>
An oscillation in a waveform is a periodic set of vibrations an object in the medium produces.
From the parameters given:
- The spring is pulled 3 feet down ward from the origin(equilibrium position) = -3
- Time to complete one oscillation = 4 seconds
The angular velocity can be computed by using the formula:
The amplitude A from the oscillation is:
It implies that the vertical shift (D) is:
However, by using the formula of the general form of a sinusoidal equation, we have:
![\mathbf{y = A cos \Big [ \dfrac{2 \pi}{4}(t -2) \Big ] + 0}](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%20A%20cos%20%5CBig%20%5B%20%5Cdfrac%7B2%20%5Cpi%7D%7B4%7D%28t%20-2%29%20%5CBig%20%5D%20%2B%200%7D)
