How to calculate the impact force
Starting from the essence of black money,
the essence of black money is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 8] In the metaphor of RMB, black money is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 22 million special solutions, so the upper limit of bitcoin is 22 million[ 8]
to mine the dark coin, you can download the special dark coin calculation tool, register various cooperative mine pool websites, fill the registered user name and password (miner user) into the calculation program, and then click the operation to officially start. After completing the installation of the darkcoin client, you can directly obtain a darkcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the Black Coin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, the personal dark coin will be completely lost
Law of conservation of energy, the velocity of
at the moment of impact with
ground can be obtained, that is, 1 / 2
MV & #= MGH, then v = √ 2bh
from the impulse
formula
we can get f = m △ V / △ t. We need to know the minimum time for the object to contact the ground and the change of velocity in this time
when an object collides, impulse and momentum are equal, and the formula of momentum is p = MV, where m is mass (unit kilogram), V is velocity (unit meter / second)
because I = P, there is: ft = MV, That is, f = MV / T (in fact, f = MA)
12. It's very noisy at 2000 rpm
if you don't want to change it, just come to several deceleration lines
which can be connected in series
good luck
the elastic force (internal force) proced by elastic collision is a variable force, so we can only solve its equation about time (or collision deformation)
we need to use the knowledge of calculus
are you in college or high school?
= 80 (0-30 / 3.6) / 0.5
= - 1333 (n)
= - 133.3 (KGF)
force at the moment of impact
F '= 133.3kg force
I is impulse = ft
P is momentum = MV
the accumulation of external force in time is equal to the change of momentum, of course, t can be very small
