Referring to the image to the right, the mass of block 1 is m1 = 3.4 kg while the mass of block 2 is m2 = 8.6 kg. The coefficient of friction between m1 and the inclined surface is μ = 0.31. The inclined surface is at an angle θ = 31° above the horizontal. Part A) Write an equation for the magnitude of this system's acceleration. Use the variables from the problem statement together with g for acceleration from gravity in order to write your equation.

Part (b) Calculate the magnitude of the system's acceleration in m/s2.

a= 4.14 m/s²

Explanation

We calculate the weight component parallel to the displacement of the block:

We define the x-axis in the direction of the inclined plane , 25° to the horizontal.

W= m*g   : Total block weight

Wx= W*sen25°= m*g* sen25°

We apply Newton's second law :

∑F = m*a (Formula 1)

∑F : algebraic sum of the forces in Newton (N)

m : mass in kilograms (kg)

a : acceleration in meters over second square (m/s²)

Problem development

We apply the formula (1) to calculate the acceleration of the block:

∑Fx = m*a

Wx = m*a

m*g* sen25°  = m*a  : We divide by m on both sides of the equation

g* sen25° = a

a = g* sen25° = 9.8* sen25° = 4.14 m/s²

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
