Answer:
6.28 m/s.
Explanation:
Given that,
The mass of the object, m = 0.2 kg
The radius of the circle, r = 0.5 m
It takes the object 0.500 s to complete one revolution.
We need to find the translational speed of the object. Let it is v. We know that,
So, the transalational speed of the object is 6.28 m/s.
Heya!!
For calculate period, lets applicate formula:
<u>Δ Being Δ</u>
T = Period = ?
f = Frequency = 660 Hz
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The period of that wave is <u>0,0015 seconds.</u>
<u>Δ IMPORTANT Δ</u>
The period is the INVERSE of the frequency. (T = 1 / f).
And the frequency is the inverse of the period (f = 1 / T)
Good Luck!!
A baseball would hit the bat harder. This is because the baseball is a lot heavier and more dense than the plastic ball. The keyword that you're looking for is density. The baseball is dense.
Let us assume that W is the width of the border tile (with the units of ft.). Also, let A be the are which is equivalent to 296 sqft.
<span>We establish this mathematical equation:
(28+2W)(42+2W)−28×42=296
</span>
Then algebraically manipulate:(14+W)(21+W)−14×21=74
<span>W2+35W−74=0</span>
Lastly, we factor:
(W+37)(W−2)<span>=0
</span>W=2
<span>a = ΔV/Δt = (5000-10000)/60 = -500/6 = -83.(3) m/sec^2</span>
