Answer:
Part(a): The average acceleration is during the first 6s.
Part(b): The average acceleration from 6s to 8s is zero.
Explanation:
Part(a):
The average acceleration is defined as the rate at which velocity is changing with respect to time. So if '', '' and '' represents the initial velocity, final velocity, and average acceleration of a particle, then mathematically
where '' is the time taken by the particle to achieve the velocity '' starting from initial velocity ''
Given in the problem, .
So the average acceleration() during the first 6 s will be
Part(b):
During the time between 6 s to 8 s, as mentioned in the problem, the sprinter maintains the constant velocity. So the average acceleration during this time interval will be zero.
Given the time and the horizontal velocity, we can simply
compute for the distance how far the ball travelled using the formula:
distance = velocity * time
<span>Since velocity is in units of m/s and time is seconds,
therefore we can directly get a unit in meters.</span>
Answer:
De un modo más claro, los sistemas energéticos son los modos que tiene el organismo para suministrar ATP a los músculos. Como decimos, en todos los esfuerzos físicos es necesario contar con la cantidad suficiente de energía y esto viene determinado por la producción de ATP, el adenosin trifosfato.
P waves<span> are produced by all earthquakes. They are compression </span>waves<span> that </span>form <span>when rocks break due to pressure in the Earth. S </span>waves<span> are secondary </span>waves<span> that are also created during an earthquake. They travel at a slower speed than the </span>p-waves<span>.
S waves are the waves that come after the earthquake and P waves

In order to convert the ft^2 to m^2, we use the multiplier 0.09290304.
Therefore your calculation would be: 0.09290304 · 1930 = 179.303m^2 (rounded to 3 d.p)
