Answer:
6 m/s
Explanation:
Given that :
mass of the block m = 200.0 g = 200 × 10⁻³ kg
the horizontal spring constant k = 4500.0 N/m
position of the block (distance x) = 4.00 cm = 0.04 m
To determine the speed the block will be traveling when it leaves the spring; we applying the work done on the spring as it is stretched (or compressed) with the kinetic energy.
i.e
v = 6 m/s
Hence,the speed the block will be traveling when it leaves the spring is 6 m/s
Sure ! Here's one way to look at it that nobody ever tells you:
Remember:
-- A fraction with the same thing on the top and bottom is equal to ' 1 '.
-- You can multiply a quantity by ' 1 ' all day long without changing its value.
In order to convert units, you multiply the original quantity by one or more fractions. Each fraction has the same thing on top and bottom, but in different units, so it's equal to ' 1 '. Then you go through the expression that you've built, and 'cancel' things ... dividing a unit out where it appears on both the top and bottom.
Example:
How many seconds are there in 1 day ?
(Convert one day to units of seconds.)
(1 day) x (24 hr/day) x (60min/hr) x (60 sec/min)
That's 1 day, multiplied by 3 fractions. Each fraction is equal to ' 1 ' because it has the same thing on top and bottom, only in different units.
Now, look at the first 2 terms. They have 'day' on top and 'day' on the bottom, so 'day' can be 'canceled' (actually divided) out of the top and bottom.
Similarly, the 2nd and 3rd terms have 'hour' on top and bottom, so 'hour' can be canceled and disappear from the whole expression. The 3rd and 4th terms have 'minute' on the top and bottom, so 'minute' can be canceled.
Finally, the only unit that's still there and hasn't been cancelled is 'second'. The whole expression now says
(1) x (24) x (60) x (60 seconds) = 86,400 seconds
and <em>there's</em> the conversion of units from 'day' to 'second'.
The whole trick is to pick the right fractions, and to decide whether to write each fraction either right-side-up or upside-down. The idea is to decide which unit you want to get rid of, and then arrange things so that it's on top once and on the bottom once, so that you can cancel it and make it disappear.
And that's what I can give you on the topic of converting units. To me, it's always been very helpful.
Answer:
a) m_v = m_s (()² - 1) , b) m_v = 1.07 10⁻¹⁴ g
Explanation:
a) The angular velocity of a simple harmonic motion is
w² = k / m
where k is the spring constant and m is the mass of the oscillator
let's apply this expression to our case,
silicon only
w₉² =
k = w₀² m_s
silicon with virus
w² =
k = w² (m_v + m_s)
in the two expressions the constant k is the same and q as the one property of the silicon bar, let us equal
w₀² m_s = w² (m_v + m_s)
m_v = ()² m_s - m_s
m_v = m_s (()² - 1)
b) let's calculate
m_v = 2.13 10⁻¹⁶ [()² - 1)]
m_v = 1.07 10⁻¹⁴ g
1450.4 newtons has to be applied so the object can move , because At average gravity on Earth (conventionally,g = 9.80665 m/s2), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple's weight.
